Very good you are bringing these issues to people's attention. Many blindly trust or take a chance. I've often worried what goes on behind the scenes in cafe's etc. Even someone making sandwiches or serving a buffett. Not all use plastic gloves and if they do, they could have germs also. I worked for a bit as waitresses and in kitchen. Kitchen was clean, tidy and organised but I felt there wasn't priority in the hotel to things like hand sanitisers and they had none. Also I noticed a chef wipe his nose with his hand and put his hand back in his overall pocket. Then he went back into kitchen to work!
