Unless she’s a regular who you’ve been getting a deal with or she’s not very marketable pay her 5,000 pesos plus transportation cost. Personally I don’t count food/drinks since most girls will be happy with beer, plato del dia and maybe pizza in the evening. Anything more than that i view as a gift. I’m not fond of 18-24 hour deals because I get bored easily; however, when I do them I always considered the money I’m saving. If you got an appetite 2 STs and a TLN could cost 9,000 pesos so if I pay her with transportation 5,500 I saved at least 3,500 pesos
