Cup of Coffee
A cup of coffee in Lebanon is not literally a cup of coffee. A cup of coffee is the unescapable, unbeatable, signature pin move of invitations; except it is not exclusive to steroidal freaks as sweet old grandmas can apply it with equal effectiveness.
But I have a meeting. Oh come on it's just a cup of coffee.
I don't drink Coffee. We'll make it tea then.
Just had tea. Then have a Baklawa.
On a diet. Have a cigarrette.
Hate cancer. Just have a glass of water, no one can refuse water.
Do not resist, it's futile. You might slip out of any other unwanted invite, but not the cup of coffee.
Just accept it and try to enjoy the 30 minutes (if you are lucky to get out in 30) of Lebanese hospitality.
P.S. Don't think that if you just went through a cup of coffee you are immune, as they tend to come in bunches.
