In Malaysia if you looked like you were staying in the bar for a while they’d give you tiny cups of coffee between rounds. That way, I guess, you’d be awake and buy more drinks.
Never been to Malaysia... had to keep up with the locals in Pittsburgh in the 70’s. That was hardcore. Interesting, but don’t recommend it.
Of course, it was still safer than Amagusto’s in the South Valley of Albuquerque... just ask Squantos.
PS: You might want to get Mom’s permission on that one. :)
