I think what you're doing is wrong and borderline criminal. Not only do you wait for 5PM to drink, but you intentionally delay it by another 15 minutes by putting cold beer into a freezer.
Beer (or any drink) when consumed ice cold deadens the taste buds and reduces the amount of flavour you will experience.
Coors Light is the perfect example of marketing and science joining together to fool you. Chill until the mountains on the can turn blue which is too cold. Ever try a Coors Light at a warmer temperature? It's horrible!
You should do 2 things:
Buy better quality beer, ideally local and fresh. If the brewer recommends a temperature follow it.
