$1 debts and ketchup

So today i had to go into the bank that i used to have an account with and pay this mysterious $1 debt that they were pestering me about. i'm not sure how i got a $1 debt in the first place since i completely closed the account and then apparently i spent the one dollar. anyhoo, i go in to pay this one dollar and i get bounced around to three different people because no one could take the one dollar. as i'm standing at one of the windows i notice there is a bottle of Heinz ketchup on the other side of the glass. i checked the bottle to see if there was anything special about it, but it was just a normal bottle of ketchup. i thought, maybe this lady is personalizing her window and she feels an infinity towards ketchup, so i leaned back and looked at the other windows. They all had ketchup in their windows. i turned around, and every desk had a bottle on it. the following conversation then took place:

'Out of curiosity, why do you have a bottle of ketchup in your window?'

'To boost our sales.'

'You sell ketchup?!'

'No, to boost our company's sales.'

'Your company sells ketchup.'

'No.'

So i stood there incredible confused as to why these random bottles of ketchup were in the windows. A guy down a few windows heard me ask and decided to ask his teller also, 'Why do you have bottles of ketchup in your windows?' 'You sell ketchup?!' Apparently, he didn't get a clear answer either.

This whole thing made me thankful for not doing business there anymore because i just can't trust a bank that mysteriously keeps ketchup in their windows or a bank that would have close ties to Theresa Heinz Kerry.
