For those who want to do some reduction of exposure..... there are some pretty easy ways to reduce exposure if you are a nomad.
I have a box of disposable vinyl gloves I use when doing fiberglass, painting, greasy stuff to wear for projects where washing them is not sensible. Those work just fine for using at a gas station including if you have to go inside to pay. Toss the gloves into their trash can instead of taking them with you into your own vehicle.
You can also do this same thing in the grocery store with the gloves, there is often a trash can outside the store. Try to go to grocery stores with a self checkout aisle and use your own stylus on the screen. Then use a small pad of alcohol on the tip if you are truly worried. Choose the products at the back of the shelf instead of the boxes or tins in the front. If they have been touched it will hopefully and also sometimes likely be enough days that the virus may no longer be viable. Take along your own folding, rolling cart instead of using the one at the store. You can use sanitary wipes or alcohol dampened paper towels to clean plastic bottles you buy, plastic packages, on cans and on cardboard boxes. It does not matter that much if the ink on the paper gets a bit wet, remember it will dry quickly. Yes you can have your beer, aluminum cans are easy to clean. You can wear those disposable gloves to do the sanitizing step if you want to but the wipes are going to have sanitizer on them so that will keep your fingers sanitized as well.
And always, when you to go into any public space, when possible, choose the hours when the smallest number of people are likely to be there. Do not go at prime time such as lunch hour and at evening rush hours. Some stores are open 24 hours such as Walmart. If you stay there it is easy to shop at hours when there is no crowd around and the staffing is also minimal. The restrooms are also likely to have been cleaned before morning.
You biggest issue will be not the boxes and cans but the produce you don't cook such as lettuce and other produce a customer might have picked up to check for ripeness and quality. You might want to avoid those even in a cafe. The CDC says it is best when choosing fresh produce to stick to cooked veggies that reach a high enough temperature during the cooking time to kill a virus. The CDC has information published on their website regarding what type of produce to avoid and what are the best choices and what that temperature you need to achieve in cooking the vegetables. Remember you can cook fruits as well. Of course you do lose some of the nutritive values so take your vitamins in supplement form.
Remember they already have a vaccine for Covid 19 that is now in the testing stage. Plus several more versions of vaccine in the development stage. Hopefully there will be a vaccine available before or at least early in 2021.
On the news this evening is that many large corporations are stepping up to help find the fight to get this virus contained and to help offset some of the cost for providing health care workers, supplies, housing for people doing quarantine, etc. So are the cities, counties and states. Some real "crowd funding" of large dollar amounts is happening.
