Can someone please explain this to me.....

HP03 & HP04 head to the sushi place in the Sizzling Express this afternoon to pick up lunch. We place our order and are killing time walking around looking at all the different things they sell while waiting for our sushi. HP03 makes a beeline for the candy and we're looking at all the different japanese treats they have when HP04 looks up at the shelf above and what's on the shelf above the candy but baby oil.
HP04 points this out to HP03 with the comment "what a weird thing to sell at the sizzling express."
We continue to nose around killing time when HP03 leans over and says to HP04 "they also sell enema's here." Huh???? HP04 looks up and sure enough on the shelf is not just one enema but a whole row of them!
I DO NOT get this at all....If someone had to buy an enema why would they go to the sizzling express to do it? When did buying an emema become an impulse buy?
HP04 is having a really hard time grasping this one - its just so weird! However, HP03's reply is "no way man that's good to know. One stop shopping. Pick up your sweet and sour chicken and the enema"
Is this some sort of sick joke people are playing on the sizzling express owners - filling out comment cards requesting enema's???? What has happened to the good old china buffet? Someone, please explain!
