"A study by U.K. newspaper Metro found gut and fecal bacteria on touchscreens in all of the chain’s restaurants it surveyed. It took samples from the screens in eight branches and found that they contained coliform bacteria, a group of microorganisms found in people’s intestines as well as in soil and on plants."
After the restaurant waiter or cook is done texting and then flushes the toilet, they wash their hands. Do they wash their phone? Or do they put phone in pocket, go back to kitchen, and proceed to finger the phone for the next hour and contaminate everything while playing their role wearing a mask?
You're probably unaware of the high prevalence of fecal bacteria on public surfaces, then.
