I want to chuck in over exuberant shop assistants. Actually just exuberant shop assistants will do, they don't even have to be over exuberant.
This exchange actually happened today when I went to buy some floor cleaner from a 'just less than £1' shop
"Cashier number 2 please"
Me - "Hi" as I plonk down my floor cleaner
Cashier - "Hi" and he's jigging around
Me -
Cashier - 'jigging around'
Me -
Cashier - 'jigging around'
Me - "Do you need the toilet?"
Cashier - "No!!!!"
Me - "Why are you jigging around then?"
Cashier - "I'm happy!!!!"
Me - "There's a queue"
Cashier - "Yes!!!!" and jigging around
Me - "I just want to pay for this" and indicate towards my floor cleaner
Cashier - 'jigging around'
Me -
Cashier - 'jigging around'
Me - "Please, take my money"
Cashier - 'jigging around'
Me -
Cashier - "Do you want to buy some angel cake?" Making a sweeping motion over the till area towards some prepacked pink stuff.....
Me - "What?"
Cashier - "Angel cake. Do you want some?"
Me - "No"
Cashier - "Oh go on!!!!" Jigging around
Me - "No, I just want this floor cleaner"
Cashier - "But Angel Cake is lovely!!!!"
Me - "I'm diabetic"
Cashier - "
