Years ago I was a massage therapist, which is when I first became hyper-conscious about germs. Constant handwashing is a must.
Then I was a restaurant evaluator and auditor, during which time I was also completing medical training in school, so again, very aware. During my restaurant evaluations I had to complete timings while food was being prepared and all the while observing the staff and obtaining names, descriptions, and what each staff member was doing...like answering phones with gloves on, taking money and credit cards, marking to-go items with sharpies that other people had touched, etc. So yeah, there was a report write-up that went to corporate detailing all of this. Some restaurants got really good, some upper management failed to deliver the message back down to the store-management level. There were a variety of different chains I evaluated.
Chipotle for one got really, really good at what they do and they are strict on handwashing and changing gloves frequently. I haven't eaten there since the last time they paid me to go back in 2017. After eating at so many chain restaurants for free, if my friends would say, "Hey, lets go to TGIF" or similar, I would always shoot out suggestions for locally owned places instead.
