Amateur Big Foot, it was not my intention to insult you or your wife. It seems to me that your wife's incident was quite isolated. If not, then many tourists would be treated poorly due to not speaking Spanish.
I use the "do unto others" as a general rule in my life. I teach my children to treat other people with respect. If in return you get disrespect, then you hold your head up high and move on.
I did not insinuate that your wife treated the staff with disrespect. In her case she was not at fault and was treated poorly. I am refering to the many number of times I witnessed guests snap their fingers at the staff, bark at them to clean tables, etc. I apologize if you took my post the wrong way. It was not intended.
