McDonalds touch screens
Touch screen surfaces are remarkably good at keeping viruses alive such as cold, flu and norovirus (gastro). After learning this I avoid using any public touch-screen devices. If I do use one, I wash my hands soon afterwards.
I also put in place a protocol to disinfect the fleet of testing tablets and phones that my team used. It reduced sick leave by 30%.
So I prefer to give my order to an employee, who also has a much better chance of spending some money at my business, and thus delay my replacement by automation or redundancy.
