Since when did five guys become so expensive

Basically yesterday I decided to go to five guys as I remembered really liking it but when I went there I saw the prices, it genuinely baffles me why they think these prices are acceptable. A burger itself is literally 50 dirhams with a full meal being 100 dirhams, like wtf? There's many other places that have much better burgers (e.g wimpy) where I can get a full meal for the same price as one burger. I remember eating five guys with my dad years back and I really doubt he was willing to pay these absurd prices.
