I'm a bartender. I can get messages if the door person/security is having a problem customer while I am elbow deep in an ice well (plus phones are dirty so I'm not touching gross phone and then your lime wedge even if I am super religious about washing my hands with everything I touch behind bar.) I don't wear it all the time but it is a useful tool.
I monitor my heart rate cos I'm having health issues
Butttt.. I don't feel bad for these folks, mine came with my phone.
I'm in the service industry, specifically a nightclub setting, and these folks are feral now. I have a lot more fear of getting shot or stabbed than I ever did previous to covid.
Sit on couch. Put chicken between knees. Cry at netflix series made for a much younger demographic.
