Input: context story is a bit long sorry:

I work as a shuttle driver, driving employees from a corporate building lot to the grocery store they work at. we don't have a defined schedule, they employees sign-in their hours when they take the shuttle and we come and pick them up at the time that they specify. A round trip from the lot to the store takes around 10 minutes. 

one day I had two people (John and Tammy) getting off at 4:30 and one person getting off at 4:45 (Sam). I get there about a minute early and John comes out and gets in the shuttle pretty quickly, a bit after the clock turns 4:30. we wait several minutes and Tammy does not show up. when it turns 4:38 I think maybe Tammy just got caught up with something, it happens at a grocery store can't help it, John has already been waiting in my car for nearly 10 minutes even though he came out on time and I will likely be late picking up Sam if I don't leave now. So I figure if Tammy wants to take her time she can wait and be picked up with Sam.

 I take John back to the lot and I'm about halfway back (about 4:14 now) when I get a call from the store, which I answer since the car has bluetooth for handsfree. it's Tammy complaining that she's had to wait. I'm a little annoyed because since she obviously wasn't out when I left the store last she could not have been waiting more than 5 minutes from when she called me, almost half the time John had to wait for her, but I just tell her my current location/time estimate and we end the call.

I get to the store about 4:46, Tammy gets in and I let her know we have to wait for Sam. Shes upset so I explain my thought process to her but she doesnt really have a choice but to wait. Sam gets in and we leave around 4:49, getting back to the lot around 4:54-55. 

Later I get a text from my my manager that I got a complaint, it was from Tammy. I explain that her being late would put out 2 people who were getting out in a reasonable amount of time, so I chose the path of the least inconvenience for everyone. My manager tells me "It wouldn't have been a problem if you had come back to the store as soon as possible." I was confused, because I did do that. It turns out Tammy lied and said she had to wait a full half-hour before I showed up. If Tammy did not come out of the store until after 4:38, and I took her away from the store at around 4:49, there's no way this is possible.

I was reprimanded, I now have to wait a full 10 minutes after the time the employee writes on the sheet (this I don't mind since it was an order from the manager, if somebody complains due to issues coming from this I wouldn't consider it my fault) but the thing I'm more angry about is that she wildly exaggerated the time she had to wait to get me in trouble. at the time that this happened I was only a couple of weeks into starting at this position (previously in the store) and I'm not very confident in my job security because not a lot of people take the shuttle so I was genuinely worried someone saying they had to wait a half an hour could cost me my job. 

the other day I was just scrolling through random sites and I read some story about a lady who had a boss she hated or something like that so she used his number to sign up for a wake up call service set to call him at 5 a.m. every morning for a certain amount of time. at first I was like haha funny, but the more I think about it I think it's a good idea. I have Tammy's number since she has used her personal phone instead of the store phone to contact me about the shuttle a couple weeks after the incidents. Its relatively harmless, she can cancel the calls on her end, but has the potential to be very annoying especially if I sign her up multiple times. the very least she deserves is losing some sleep. 

WIBTA if I got back at her this way?
