Among others, there are four rules I live by.On a related note, I've never understood the thinking of people who go around antagonizing and belittling the people handling their food. Even if they are shiftless dumbasses - all it's going to get you is colder, slower food with more spit and bugs inside.
Don't annoy the people that handle your food.
Don't annoy the people that handle your money.
Don't annoy the people that handle your records.
Don't annoy the people that manage your health.
If I want to send a message to a chef, I will either compliment him by sending my plate back clean, or insult him by sending back leftovers.
