Car park scenario.

Scenario of two people who has not been grocery shopping for two weeks.

*Car slows down at the exit counter and Ray's hand reaches for the ticket.*
*May grabs her wallet and proceeds to take out some coins.*
"Wait wait, my wallet is heavier. I have more coins in my wallet."
*Right hand reaches for wallet. Suddenly Ray pauses half-way.*
"It's Sunday today lah."
"Oh, right."

Trust two silly geese to forget that Sunday is a free-parking day.
