Haggis Factor
A secret fee added to your bill just because the Scottish guy running the shop felt like being a total jerk.
The haggis factor came out of nowhere when I bought a sandwich. I was just trying to be polite.
My friend got charged the haggis factor for 'looking too happy' at the grocery store.
I paid for a drink and got a receipt that said 'haggis factor applied, because you’re not Scottish.'
