Halfway through my meal, some of the staff slowly started packing together the outside furniture. The waiter must have realized that I (unintentionally) was speeding up with eating, and reassured that there was no hurry, and I should take my time.
The best part came when I asked what time they close: "it doesn't matter. You take your time."
What a brilliant answer. I will be going back there. They all seemed really happy when I complimented them on their great service too.
Goes to show, you can learn a lesson from anybody.
