All the responses here are right on!!
It all depends on the chica, what she has been taught by her peers, what she thinks she can get out of the guy. and regretfully as mentioned "how much gringos have influenced the chicas"!!
Most of the upselling is at the 2 most popular gringo places, and no, the same chica does not try it with the Ticos nor in most cases, the gringos who have lived here for a while (same thing with asking for a tip!-- I have never been asked for extra -for service nor tip at HLH ). Up selling also occurs in other MPs mostly by chicas who have recently left one of the 2 above mentioned places. But usually she quickly learns that that does not fly, or she does not last. Example: a NF chica recently went to work at Relax and is trying to upsell gringos there--word got out very quickly, and though she is a very hot chica, I have not seen her session since the first day she was there. Same thing happened at la Mansion.
The 2 exceptions to all this is: 1--chicas who do not want to do BBBJ will often ask for a large upsell to avoid doing it! 2--the culo is almost always at an extra cost!!
