I like your list, except the tag ons for number four.
Some of the best beers of my life have been warm. Real men don't whine about drink temperatures.
And extra cheese is not necessary and often make things worse. Pizza, good pizza, doesn't need extra cheese and it can definitely take away from the pie if it's just a cheesy, greasy, soft mess.
maube this can be summed up in another rule:
Appreciate food and drink offered to you, do your best to enjoy it in it's best form but a warm beer and a slice of decent pizza eaten with still dirty hands around the back of a truck is awesome if thats what you've got.
