'Are you still serving lunch?'
Employee looks at the clock, that is displaying 10 past 4.
'No, sorry. Lunch ends at 4 o clock'
'Give me the lunch menu anyway!'
'I'm sorry but you're too late for lunch!'
The Stupid Customer moves over to go and sit himself down at a table.
'I'm only 10 minutes late! This is why this place is empty! You need us.'
