I used to go to stripclubs quite a bit. I stopped now. A incel-in-denial friend introduced me to them, and had me going to them often.
Want to know some bad news? Strippers approach ugly guys more readily than they approach Chad-tier or even average "OK-looking" guys. I'm hyper self-aware, and noticed it all the time in the strip clubs - I've seen muscular Tyrones, tall good-looking white dudes, and Chad Latinos get routinely ignored or walked past by strippers. Rather, I see them approaching old, out-of-shape guys and sub-5 guys of all ages, hassling them for a lap dance or even to the champagne room. They do the same to me, and then it clicked: "Oh shit, I'm like those guys!" The strip club is almost like an inverse of regular clubs or a normie party scene. The last time I went to a strip club was early 2023, after not going for nearly 3 years --- I was instantly approached by more than one, while I saw a bunch of Tyrones sitting around gawking at the whores on the stage or staring into space.
As to why strippers approach ugly guys? I can't say, but I'll take a stab: strippers (like most foids) can read men well and tell if he gets pussy with ease or not. If you look like the kind of guy that struggles to pick up girls, strippers will assume that you're desperate and will easily get convinced to pay for lap dances and even a private room.
