We learned a long time ago it is better to pay for everything with pesos to avoid the horrible conversion rates. This also means tipping for drinks in pesos. My question is, what is considered a good tip for one drink and for two drinks? In the US, I will tip $1 and $2 respectively on a per serving basis. If I'm tipping at the end with a full bill, I tip 20% or more. Since we don't have drinking bills at the resort, I was thinking between 20 and 40 pesos. (20 pesos = $1.13). I don't mind being generous, but would prefer to be "just" on the good side of the scale.
