Interesting theory

The pina colada thing was just part of his act to make it seem like he didnt drink. Therefore helping Pam to trust him to get a ride home and so he could crash into the girls and not be faulted for it afterwards.

I think there’s also another reason why he drinks virgin pina coladas, while the girls drink alcoholic drinks.

he’s planning on smashing into them at that point, and he knows if he gets into an "accident’ with alcohol in his blood he will be charged by the authorities. But as it was… the girls were drinking and the “accident” is deemed their fault, therefore Stuntman Mike gets off scott free.
