OK.
It's not just Cafe de Coral, it also applies to Maxims, Canteen etc.
Why, once you've finished your food, and your still happily sucking away at your drink, do the staff ask you if you're finished and then proceed to take the tray away?
Surely, they should wait until you've completely finished your meal AND drink? I mean, once they take your tray away, they only have to come back for your empty glass anyway!
Does clearing away the tray, but not your drink, somehow makes it look tidier? Is there a reason behind this?
The ONLY time this does not happen at these place is if, I FINISH me drink before I finish my meal, which is rare.
Shed some light!
