In my own personal experience these uneven fees impacts how often PCs frequent different bars and clubs. I bet that if you tracked how many PCs enter each bar or club every day, the one with no fee would have far more visits than the others. I suspect you would also see that bars and clubs with lower fees get more PC traffic than those with higher fees.
Again, I don't know any of this for certain but my own limited experience supports it. I've even had a PC say that they go to club A more than club b because club b cost 5 chyen more to enter. I doubt they are alone as I also tend to pick the cheapest club unless I have good reason to go to a more expensive one.
Maybe this is intentional and staff wants specific clubs or bars to get more traffic than others when not run by a player. Maybe staff simply didn't realize that players would let even 5 chyen influence their choice of bar or club. If this was an oversight, I'd suggest making it so all bars and clubs that are not leased have the same fee so that the incentive to visit one club or bar over another lies more on the players.
