You'd like a sandwiches? Sure, what kind? While I'm up, I think I'll have a beers too. Or is that two?A Roman centurion walks up to a bar and tells the barkeep "I'd like a martinus, please."
The bartender replies "Don't you mean a 'martini'?"
The centurion responds back "If I'd wanted more than one, I'd have asked for more than one."

As bad as my Italian is, I'm always annoyed to walk into a place to see "a panini" on the menu. "Panino" is singular, "panini" is plural.
"I'd like a panini, please" is "I'd like a sandwiches, please."
