Lol, I’ve never heard of one of those but it sounds excessive and would be seen as such especially when with friends after a night out when grabbing a kebab or burger. It’s just one short stop before putting on the white gloves and running your fingers around the establishment before pulling out a clipboard with hygiene related questions to grill the owners with, I think I’d be quickly given a white coat to go with my white gloves.
Try going abroad and eating street food whilst gazing at the feral dogs, cats and rats under your table, take that trip advisor! Lol
