to be fair it was probably a call service rather than an actual bar (even tho yua claimed to work at a Girls Bar)
and hm, hard to tell with that art style but i don't think that other customer looked particularly like an 'old hag' compared to the older male customers Yua had, i'm surprised there wouldn't be more 'granny' or mid 40s aged sugar momma type women coming to the host clubs tho i guess this arc is more focusing about the 'younger' customers struggling to pay for it, b/c someone in their 40s going to a host club i assume wouldn't 'struggle' to pay bills to where they'd also be propositioned into the sex industry even if there are some ppl who would wanna sleep with someone older/the same age rather than college aged girls
