I just remembered a couple:
Halloween one year a couple of guys were dressing up in little kid clothes as Batman and Superman. I would understand adult ones (I'd be Batman myself) but not little kid ones where you see their "buldge"
Another time, some old guy comes in asking where the personal massagers were and called them dildos
. I told hime the asile, cause gross and asked me to show him where they were. We didn't sell such things (they don't say they actually are dildos, but come on) at the time.
