Input: Text: so, i work in retail. as in all retail jobs you greet customers. i like greeting customers. when i see a customer i greet them, "hi, how are you", "hi, how's it going", or some cheeky pun relevant to the person. i usually walk around my store and greet people. apparently this is a bad idea, you never know who is trying to get away. 
so as i'm walking i see a lady and her friend that i didn't greet. i start walking towards them and ready greeting. just as i'm about to say hi the lady let's out a loud foghorn machine gun fart. in an effort to save face and not laugh in hers i turn around really quick and try to muffle my laugh. before i can take a step to walk away she let's out another one, this time obviously a butt clenching squeaky fart (she was trying to stagger it and let it out quietly). i lose it. she's upset and demands to speak with my manager about the maturity level in a store of this caliber (i work in high end retail). tells manager. manager pulls me aside and asks "soooooooo, a customer farted and you laughed. (i laugh again)" once i started laughing she started laughing and she tells me that she can't even be serious about it so just come out and look upset to make the woman feel accomplished. 

 
i stuck up on a customer who was trying to fart in peace
