McDonalds has consistency issues..
To get hot fries or food in general these days you have to go in and custom order and wait and I am way too lazy for that.
The filet of fish if it comes out just cooked is cool but 90% of the time it will be a soggyass mess like most stuff they serve.
I think 90% of the reason people love In and Out is everything always comes out hot and fresh off the grill or out of the fryer. Their quality control is second to none.
