I remembered something from nearly 20 years ago we went on holiday to some place near Cancun with a stop over in Mexico City... We ordered a few drinks in a bar in the airport on the stop over and I nearly had a heart attack when I saw the bill.. I thought it was in US Dollars but I didn't know the Mexican Peso used the same symbol... I made a right twat of myself when I pulled the barman in a panic over the bill...
I had the same shock the first time I went to Beirut.
I had a few beers in an English pub. I asked for the bill and the English barmaid said "Thirty pounds". I nearly crapped myself (this was in 1975 so it seemed a bit pricey for a few beers).
"Thirty bleeding quid for a few beers".
"No. Not thirty quid you twat.. Thirty Lebanese pounds (livre)".
Phew. This was about a fiver. Still a bit pricey for the time though.
