I love

when people say "this isn't what they charge me at (insert geographical location of other store)!"

Particularly when they're on their cellphone and are half complaining to me/half bitching to the person on the phone

and I can't explain to them that they're actually getting a better deal than they would any other day because flavor's included for free today

and if they'd look at the fucking menu they wouldn't have to bitch at me and tell the person on the phone all about how inept we are and how they're going to start going someplace else.

Good job, person. Good. Job.
