HOW TO DISTINGUISH A PORTUGUESE FROM AN ENGLISH PERSON IN A LISBON-LONDON FLIGHT

The Portuguese person will open the sandwich package on top, slide the sandwich up like a lipstick and eat it without getting their hands dirty; the English person will rip the package open in the middle, take it off altogether and eat their sandwich spreading crumbs across their seat and everyone else's. Then, the Portuguese person with clean hands will open the napkin package, take it off and wipe their already clean mouth and hands; the English person will most likely not even notice there is a napkin there unless they somehow need sugar for their tea - very unlikely. If they do, they'll take the sugar off and leave the napkin inside, untouched.
