You go through the simple retail shop itself when you bring any item into your shopping cart before you step up to the female cashier, but also single. She looks at you while she is putting your stuff in the retail bag without messing up your paid order at all.

"Hi there! I see you brought those items, by the way. I'm Emma, that's my name. So, go on. I'll check up on your item, and you'll pay for it."
