anyone know what a "silent irritant" is in the bar/pub setting?

Farts.

 

I do indeed

It's stuff like.....

1. smokey atmosphere
2. pinch points where you have to squeeze through
3. inappropriate lighting levels
4. bar staff reading magazines in quiet periods when they could be cleaning the scruffy bar.
5. tables and ashtrays not being cleaned.
6. temperature too cold /warm
7. smelly pub / bogs
8. bandit in inappropriate place
9. pool table in room not large enough for cueing
10. Miserable landlord with egg stains down vest
11. Weeds growing on patio / car park
12. blown lightbulbs not changed
13. beefburgers like hockey pucks
14. that deaf, dumb and blind kid that sure plays a mean pinball

 

It's the ******* who goes deaf and mute when someone asks: 'Whose round is it?'

 

I left myself off the list, but well spotted, I was number 15

your round.
