Just thought I'd throw that out there, because a few times in our almost-month here we've had moments where a) things were on the bill we didn't order (in Chiapas) b) it was added up incorrectly (Il Borreto) or c) tip was added automatically but not indicated as a tip (Playa Maya).
In particular, the last one at the Playa Maya troubled us. On the bill it read in spanish "Propina 12%" and added the 12% to the bill. Then at the bottom of the bill it said in ENGLISH "Tip Not Included". All of this is not handwritten, it is typed into the receipt by the computer.
Now my husband does not know any spanish, so he added another 15% to the bill for a tip and laid it down. I picked it up and took a look at it, and noted to him that "Propina" means "tip". So in other words, they added the 12% tip already, then say that it is not included. This seemed sneaky to me, being they were both written in different languages, so a non-spanish speaking person would definately be led to believe that the tip was not included.
Just thought I'd throw the warning out there!
(btw...Babe's also includes the tip in the bill!
