When I worked at a café I definitely was handling cash a lot more and people's credit cards and what not, so I always felt like being extra cautious with physical health stuff was important. Although these days at the café I used to work at they have a lot of ways to pay without the associate or barista having to handle credit cards (unless the customer wants to pay cash). But yeah, I didn't get a flu shot this year and I paid for it (I didn't get all that sick though so I'm not sure it was the flu in reality).
