Zaatar W Zeit started charging delivery charges few months back, then Roadster Diner and Deek Duke followed. The charge is 2000 Lebanese Lira regardless of the distance and was set to maintain the quality of the delivery service, as I was told by all three restaurants.
Honestly, Zaatar W Zeit is the only one of these three that needed an improvement in the delivery service and I haven’t seen any major improvements ever since the charges were implemented. Roadster and Deek Duke have a perfect delivery system so the delivery charges are unjustified to me. In fact, it is letting customers tip the delivery guy less because they’re being charged for the service, so unless the charges are going to these guys or they got some raise, they won’t be too happy about it and quality will eventually drop.
