I went with my kid to Legoland a few years ago, and both of us remember this lady cut in front of us at the food line to complain about the pepperoni pizza she ordered.
She went on a tirade that the personal pepperoni pizza only had 4 pepperonis not 5 or more and demanded a full refund. The manager gave her a full refund, and then she sat down and finished the pizza.
I feel sorry for the american retail stores. What a pain in the ass american consumers are.
