so this did happen today, i actually just got off of work. just a bit of back story first. i work the night audit at a hotel trying to turn itself around. we had a block of about 60 rooms staying with us from the vfw for a convention they were having at our hotel over the last three days. i had just come back from a few days off, and there was an email printed off at the front desk from our sales department saying a few of the vfw rooms might not be used tonight only, and to not charge them for it for the evening. here's where the fuck up happened.

early in the morning i went through the remaining arrivals and charged them for no call/no show. i then  went through the block list and saw that they still had 46 rooms that hadn't checked in,  so naturally i went through and checked them all in and then out, without charging them for it. these rooms were supposed to be at a group rate of $225 per night per room. i did of course think it was odd that so many rooms weren't being paid for, especially since this was $10,350 worth of revenue, but then assumed that maybe sales worked out something special with them regarding the amount they paid. after not charging them, i sent a group receipt to the main vfw email we had showing that they hadn't been charged for these 46 rooms. 

at about 6 o clock this morning my front desk manager calls me and says, frantically, "op, we just got an email from the vfw thanking us for not charging them for the 46 rooms that couldn't make it last night. why the fuck weren't they charged?!" i replied, "we have an email up here from sales saying not to charge them for the rooms that didn't show up." after i said this it was silent for a while, during which time i could literally feel her mouth-frothing anger from over the phone. she whispered, "op, did you happen to check the date of that email?" my blood ran cold, and shakily grabbing the paper i saw it was dated from the first night of the convention, a few days ago. i didn't even know what to say, so instead i mumbled a few things like "oh shit" and "fuck me". she said, "steve (the owner) got this email too." knowing i was too scared to even ask his response, she painted this picture of his reaction: after having a heart attack, steve realized he would no longer be able to afford one after what i did, so he cancelled having said heart attack and instead booked the earliest flight to my city that he could get, leaving at 5 am tomorrow morning. i'm fucked guys.

update: i want to thank everybody for their suggestions in a resolution, i actually used many of them. that being said... holy. shit. i decided to go back to work to call the head of the vfw chapter and explain what happened. when i got back to work steve and the front office manager (fom) were having a meeting. so i called the chapter head and told him what had happened. he said that it was fine, and to bill them for the 46 rooms. i made a choice here based on some suggestions from you guys, and asked if i could charge him for 30 of the rooms, and "donate" the other 16 to the vfw for the night. he said of course, and told me that he would spread the word about our hotel's generosity in donating to the vfw, and proceeded to ask me to transfer him to sales so that he could book their next event with us.

i went home, and a few hours later steve called me to the hotel for a meeting. i went, piss-ass nervous i might add, and met with him in his office. he said, "op, do you like working night audit, or would you be happier somewhere else?" not sure where this was heading, i replied, "i enjoy working at this hotel very much sir, but i will gladly resign over this." looking bemused, he told me that while i came back and talked to the vfw, him and my fom were discussing how to fix this issue, and that she sat there the whole time insulting me and blaming me for everything. he then told me that he was so impressed by the way i handled the situation, that he would fire our fom and spend the next two weeks training me to do her job, as he was very unhappy with her performance in several areas. so, thanks to you redditors, a stupid fu turned into a promotion with a move from hourly to salary, a pay raise, and better hours. thank you all so much! :)
