Meeting a friend

Hi, i have a meet with a friend tonight, i want to go, but at the same time i dont want to go. The reason is that he basically used me alot as a uber, since i had my drivers license before him and a car too. I used to drive him for basically 2 years from school to home, because i felt sorry for him since his busses drive so bad and because hes my friend. Now we will meet tonight at a bar to drink and what issues me is that i wont be able to drive with my car (dont wanna pay for a taxi) if i want to drink and even if i dont drink i will be forced to drive him home too, because then he would be alone and since he lives basically on my way home i feel obligated to drive him too. He never has driven me with his car, or has done anything really for me, like i even took him back home when he wasnt able to even walk because of his drunkenness. Idk what i should do, thanks for every response
