Personally, I feel like the majority of people have worked in retail at some point in their lives...which is why we ALL can relate to the annoying things customers do while shopping.
Maybe it pisses you off when your shift ends in 10 minutes, and then that ~one~ customer walks into the store to buy something.
Perhaps it's when you've nicely folded the shirts and then a customer completely messes it up within a matter of seconds.
Of course, it could be when a customer attempts to return something past the deadline, without a receipt, or that's clearly been worn...multiple times.
