Damn right sure no adults would feel "nervous" buying stuff at Disney stores; they always give you that no-stress feeling...
I am not nervous walking into any toy aisles at all. Shoplifter-kids are more nervous than you when you walk in there.
I am proud to collect the things I like. I even have some small figures at work on my desk.
At the cashier:
"Would you like a bag?" No...
"Do you need a gift receipt?" No...
"Do you have Air Miles?" No...
"Would you like to donate $1 to the _______ ?" Sorry, no...
"Are these for yourself?" YES!!!
