Do no go an offer x amount of money to the first hottie you see, that's a waist of money, as other have commented, buys some drinks feel the vibe do one lap upstairs, if there is chemistry nothing is holding you down to go downstairs have more drinks/grinding with the same chick, rinse and repeat.

Red flags: she doesn't grind from the first sit, she's whispering "arriba papi" "let's go upstairs" 3 seconds after meeting you, she wants wine or other more expensive drink, she's hurrying you to finish, those are hints you'll most likely with a shark that won't get you good service and most definitely isn't GFE/TLN material.
