At Universal - you just eat it. What you have are small groups that are eating or drinking and everyone just social distances from the other groups. There are some areas with tables along / near the CS places to eat, but not by the carts. They do not want to see everyone with the mask down walking and drinking / eating. They ask you to pull the mask down to take a drink when walking, if feasible. In all the restaurants, everyone takes there masks off when seated for the duration of being there. same if your sitting at a bar or side table or table outside. At Volcano Bay, you put your mask on when getting in line for a bar or to order food or go in a shop, but keep it off otherwise. Disney is going to be acting in a similar fashion. They have the social distancing lines/marks set up in lines, lines for carts, lines for CS, lines for stores, etc. Where they don't, people are pretty good about avoiding others and keeping their distance. This allows for eating and drinking in most areas.
