The answer to a lot of these questions is that you do what everybody else is doing. Grocery stores, restaurants, home improvement stores - their cost of doing business all went up. So you adjust your cost back to the customer as best you can and tweak your business model as best you can. With regards to crowds, I don't know about where you are, but we have a maximum amount of people allowed in a grocery store (for example) here. Outside on the sidewalk are orange painted Xs 6 feet apart. Someone monitors the entrance, and if the store is full, a line starts forming outside, 6 feet between people. Obviously if you pull up and see there's a long line of 30 people outside, you'll go find something else to do.
Maybe they charge double to bowl because of all the required sanitization and having every other lane open and what-not. Maybe people pay that because they're desperate for something fun to do. Maybe they don't and the business tweaks the way they do things or closes back up.
