I served two shots of baby guinness to these two forty/fifty somethings in two different types of shot glasses(one tall one and one that was smaller but wider)they thought that there was more in the small one and they refused to pay for them i had to explain to them that they were exactly the same, it went so far that i got two identical glasses and poured water from one to the other, they eventually realised that i was right.they also thought that it came from a tap... it made me smile.it was all they drank for the night.

god bless the true culchies of ireland.
