This waiter drops everything and runs after customer who left a generous tip with a note

Though not always the case, it was common practice for David to take payments via credit card, and therefore the customer would need to ask for the card machine.

Some might even wait to collect their change if they were paying by cash, but neither of these seemed to apply to Steffen Berr. David noticed something unusual about Berr’s bill, and it sent shockwaves through the waiter! Grabbing the bill, he looked down and was shocked by what he saw.
