I actually did have a date once that brushed up against this rather close. I was unaware her parents were very straight, bland, and religious, and we ended up having dinner much like this, only in a much more white, sterile setting with awkward conversation and me being asked to carve the turkey despite not knowing shit about how to properly carve a turkey.
I don't think they liked me much.
But at least the dad did not ask me to look as his knees.
