Mexican here.
Your first plate will be made for you, so you’ll be asked if you don’t want something. The same way for your drink: milk, soda, beer, ice, no ice, etc.
Eat as soon as you get to the table
No talking or chewing with your mouth full.
Tortillas at almost every meal. Yes, this includes soups and some relatives have used them on spaghetti. If you can’t use them, please ask for utensils. However, forks will be provided for salads.
Fork and knife in either hand, just make sure you get the food in your mouth and not on the table. Personally, I switch hands several times in a meal. Same goes for drinks, but they’ll initially be at your right.
After eating the first serving, if you’re a guest, take as much you want. We have plenty of food in the house.
Since I mentioned it, please don’t bring any food or drink as a gift. It can be seen as either our food isn’t a sufficient amount or good enough for you. Holidays are exceptions.
If you can’t reach a dish, ask for it to be passed.
Your plate was brought to the table, it will be taken back the same way. Leave it there.
If a guest, prepare to take food home. Please remember to return the plate/bowl/etc.
If you’re invited to a restaurant, order what you want. DON"T ask to see the check or offer to help pay.
