both guys involved more or less unknown but reggy over sth like a 20 hand sample

Not sure if I'm better off just folding preflop at these stakes but 88 seemed still good enough to call. I'd probably draw the line either at 88 or 77 though.

Seems like a fairly trivial call given that he can have a bunch of missed overs and flushdraws.

Here I'm not sure at all. Given that after his bet there will only be 9$ more left over I don't think I can call here or at least it doesn't seem to make much sense. He can technically of course still have some FDs or A high overs with a gutshot but it doesn't feel like the average reg has enough bluffs in his range to ship in 88. Might of course be wrong about it though. WP if I fold here or do you suggest anything else?
