Mcdonald Diepkloof Square Drivethru sucks. No communication

Went to McDonald's Diepkloof Square at 19h25 queued at the Drive Thru till 19h50 with more than 12 cars behind me, when it's my turn order the cashier closed the window with no communication that she's closing. It would have been better if they advised us not to waste time and petrol queuing when we get there than the attitude they gave us.

It really sucks. No more going there and will advise others of this bad service.
