Four beers, wow ! Hope you didn't burp! Which is what I did once after downing a few swallows before the meeting one time, that was years ago when my digestive tract was still in it's 20's, however, that burp, although silent, did give a major hint that I had a beer sometime during that evening.
Surprising that my elder dad didn't say anything about it since he was two seats away from me . . . oh, now I get it, he was probably counting the time till he could get home so he could pour his Johnny Walker Black Label. Which I can remember him doing since I was about 4 or 5, although he didn't come into da troof until I was a teenager, he tried to give it up, but just couldn't do it, like many others elders, who probably put forth the effort but found out most of congregation were drinking fools anyway.
