I would draw the line a little further away than a drink for the ride home, or even taking one or two drinks home with me for the drive the next morning. It's in their best interests if you make it to and from work happily and safely. If a drink makes the commute easier, it's worth it.

As an example, I asked my employer if I could borrow my steel toed boots meant for site visits to use during some work outside to help a friend for a weekend. I told them if I damaged them I would gladly pay to replace them. My boss told me that they would lose much more value from me missing work injured than those boots would cost to replace, so not to worry about it and then gave me a fatherly lecture about being safe using a chainsaw before digging out safety glasses to send with me.

It's hard to make a bright line for abuse, but for a general rule I won't take anything or take advantage of anything I wouldn't pay for myself without asking ahead of time.
