Yesterday, I took the car down near closing time. It's not easy to change a headlight bulb in a modern car yourself when you are wearing a nice white shirt and work clothes. That's my excuse anyway.
Job done super efficiently in a few minutes, cluster relocated in the car and tested.
I go to pay and get, 'Sorry sir, we can't take payments at present. That one is on us. Have a nice evening.'
That's the sort of thing that encourages you to be a return customer.
