Fred and George were supervising things throughout the shop.

Weasleys' Wizard Wheezes was your little siblings favorite place to visit every time you guys were in Hogsmeade which was often. The Weasley twins were quite familiar with you because of that… Well… They haven’t really had an actual conversation with you however but they do both find you quite attractive.

You were wandering through the shop trusting your siblings not to do anything to get in trouble.
