joke

An old couple walked into a fast food cafe and ordered 1 burger, 1 drink and 1 regular chips.
When they sat down the woman pulls out a knife and cut the burger in half while she’s doing this the old man counts up and divides the chips equally.
The old man takes a bit of his burger eats a chip then takes a sip of drink.
The old woman just takes a sip of drink then the process is repeated.
A man sitting a table away sees this and walks over and offers to by them another meal, and the old man says “it’s O.K we always share every thing”
So they carried on with this process, till the man again goes back and says
“Really it’s no problem I can buy you another meal.”
And the woman says “No thanks it’s O.K we share everything”
Then the man says “Well so far he’s the only one who’s eating anything”
The old woman says “Well of course I waiting for the teeth.”
