I aged a year from this one!
Not a sucky customer, but worth telling.
I was ringing up customers at B&N one day. Nothing special, just ringin' em up. Then this guy comes up with his purchaces. We chat, 'cause I'm a friendly person. Now, he's wearing one of those loose fitting, blousey guy shirts over a regular shirt. My head was down, getting the bag for his things, I looked up...
...And I practically aged a year, because he had pulled back part of his blousey shirt, revealing, clinging to his normal shirt, a foot long, greyish green lizard!!
Yup, a live lizard, taking a ride on his shirt! The guy saw my reaction, and I laughed it off, but he took the cake as the most interesting customer of the day!
