Fast food is garbage. They replace the frying oil only once a week in all those McDonalds outlets.
Also, recently in one of the malls in Tel-Aviv I've encountered the shittiest and most disrespectful customer service in McDonalds; they tampered with my order; it took them about 45 minutes to get it prepared.And the place wasn't even loaded. All I asked for was a small-sized burger, and some cappuccino. They mixed up the orders, took the receipt by mistake along with the money I paid, and then denied me my meal, demanding I show them the receipt that they took. Could you believe that?
