They have the worst service one can find

They have the worst service one can find. The staff is very rude and have no manners.. I was there on the 25th of December at 23:38 to buy food, we waited more than 30 minutes to get out order and what is sad the staff didn't even care, when we asked why it is taking long we were told the is only one person that is working When I looked through the window there only 3 people in the kitchen.. the guy was rude and refused to give me his managers number nor his name Macdonald in East London has the worst service shame I have never been to any of Macdonald's shop and received the kind of service the MacDonalds in East London gives it's customers... I don't know if the issue is the management or the staff but people in those MacDonald need to be educated about efficiency and customer service also the importance of a fast service...
