Has anyone else pre-gamed (drank) in the airport parking lot before a flight?

Wondering if others have done it. I’ve parked before at an airport in a multi-level garage with relatively no one around, then had 3-4 beverages and then colected my empties, and deposited them in the airport parking lot recycling bin and headed on my way to the terminal. Saves about $30-$40 instead of having those drinks in the airport. So then once I’m past security, I’ll head to a bar and have another 2 drinks and be ready for the flight with a nice buzz.
