I have pointed out this before and this time it's to inform you that a lot of humans behave like monkeys.

Working in Restaurants , Cafes  and for that matter any place where food is served you are advised to wear gloves according to Food And Hygiene standard but wearing gloves is not to keep your hands clean as many as 99% think. They wear gloves but soon contaminate them by touching their clothing , body parts like face , table tops , opening boxes and packets..handling money .. etc but they forget the main reason in wearing gloves is for serving food and so gloves must be kept clean so they handle food ..where ever possible wear gloves but use serving tongs , serving spoons etc so your gloves are added pracution. 
Most food and hygiene inspectors fail to notice that most contanimate gloves within seconds of wearing gloves. So they are not fully safe.
