Did I push the limits of acceptable hygiene levels during the height of covid and lockdown, sure I did. But I always brush my teeth. Lost far too much money fixing them pre 2014 to allow that mistake recur. Not militant like Dave, but if I have some raw onion with a chole batura or some malai kebabs, you best believe there will be a midday brush. Otherwise gargle with water after pretty much every meal.
Dont smoke anymore, but can see this new coffee habit causing issues in public. I work from home however, so can be beastly at times.
