There are some really vile and disgusting videos going around about street food in India. Yeah, I get it, although if the dishes are prepared at home, they're divine. When I'm cooking at home, it seems like I'm washing my hands every 2 minutes.
If I were at a restaurant (and I don't care whether it were a Burger joint or Michelin starred) I'd expect total and absolute hygiene to be observed; any foreign objects in the food and I'd complain like crazy.
And that brings to mind another thing: latex gloves. Unacceptable, unnecessary and quite the opposite of hygienic on many occasions. Just because they're wearing gloves, then ok, pick up the bacon, the lettuce, the tomato, the burger and the cheese. They're also inhibitive because there's no doubt that you lose some of your sense of touch with an extra layer.
Much better use some tongs and wash your hands at every opportunity
