I mean, 1 for 20 pieces is not enough
I bought 5 pieces once but asked for1 BBQ and 1 mustard sauce and the guy just said no at first but then I asked him again nicely and he gave me 1 BBQ and mustard happily.
I mean, that bish was just being mean and not that she's doing her job. Well deserved
Keep your customers happy instead of pissing them off by ridiculous things
