Automated Petrol Pump?

Question

Okay so i was at the petrol pump. I went to fill up with €20 worth of gas. i went slightly over to €20.10. the attendant, rightly so i suppose charged me the 10c. do any petrol stations use automated pumps. You key in €20 worth and it pumps out that much exactly. not looking to patent or anything

Answer 1

We do have such pumps at some self serve stations in North America. Handy feature if you only have $20 in your pocket.

Answer 2

yup. I work at a full serve gas station and we have them. makes my job a heck of a lot easier
