why is 5 men so expensive?

So you paid $30 for 2 burgers, 2 large fries and 2 of what ever else?

You could have gotten a pound of prime ground beef, a 2lb bag of fries,  3 cans of baked beans, buns, cheese, oil to fry your fries and a gallon of soda for that price and had meals for 4 days and $10 left over for beer.

The reason it cost so much for your 2 meals is because...YOU PAID SOMEONE ELSE TO COOK IT.

Next time, Walter, do not be a lazy bum, or if you are...then don't complain on how much you laziness has cost you.

At this day and age, with the virus, it isn't a bad price to pay

Each item you order has a separate cost. 

5 Guys? Is that what you mean, the American burger chain?

Because you didn't read the price on the menu.

Because people will buy it at that price. If people stopped buying their food, they'd have to re-evaluate their pricing strategy.
