For those who will be celebrating 4th of July tomorrow, be safe, have a Plan A, Plan B and an escape route if you are feeling anxious , stressed or pressured. Bring your own drink of choice, I would refill mine when it was halfway done so that I never had an empty and the thought of grabbing something different wouldn't enter my mind.
If I was being pressured to "just have one or two" I would claim stomach/intestinal issues and leave. Nobody questions you on that one!
