Perhaps you need to have a large number of dishes available on the menu?

I did this solo after a couple attempts. One thing I did is I didn’t kick out drunk people. Maybe serve more hard drinks so they all get drunk lol.

I am not sure if customers getting drunk is directly related to what they drink or if it’s rng though tbh.

Don't kick out drunk people and you'll get it easy

Yeah, if you're serving drinks then all it takes is 2 lunch rush waves without kicking out drunk customers and you'll get the achievement.

Just don't serve anyone till the place is full. You can take the orders, just don't give them anything - the wait time on customers is pretty decent for both waiting to give an order and waiting for food.
