Been out of clubs for a while. What do you think of approaching a girl in a club who gives you IOI or you like the look of and saying "hey I find you really hot?"

My friend who isn't any better looking than me usually does this in clubs and gets a good response. Admittedly i dont really use this approach but Mark Manson models book says you should only do it if you truly believe it. If you truly think shes hot, express it and have no shame. PUA seems to agree with direct opener.

Yet TRP is against these types of openers usually as they give validation

Thoughts?
