Wimpy breakfast times

On Monday 31 Aug 2015 i sat down at Wimpy ORTIA at 09:40, i told the waitress that my boarding time is at 10:05, i immediately ordered breakfast, 2 eggs and 2 franks and coffee, the waitress was nowhere to be seen until i received my coffee at +- 09:55, still no breakfast, i was on the Margate flight and because it is a small flight, it is a quick boarding time, at 10:05 i was called to the flight on the intercom system, i stood up and looked for the waitress, found her eventually, but now the cashier was missing, the waitress said i had to pay because the breakfast is coming, i did not even finish my coffee, i got a boarding call again, to prevent an argument, i had no time i gave her a R100.00, she couldnt tell me how much or what change was forthcoming. Is 25 min enough for breakfast, not happy
