The only thing that I have purchased that made the cashier give me such a weird look was a sex toy. My partner need clit sucker and I got that for her but it was shocking to the lady cashier I picked that out to buy.
I would say the weird things you could buy at a grocery store that would get you weird looks by the cashier would be cucumber, lotion, and condoms. All those three bought together by anyone would get weird looks from anyone LOL
