Burger King Gateway Does not have any customer service.

Burger King Gateway is a customer service less branch. They made us wait 15- 20 odd mins in the queue only to get to the counter and tell us they are only accepting cash, no cards. I have a 30 mins break of which more than half of it was spent in line there. The manager or atleast Im assuming its him was standing by the counters the whole time, saying nothing and then he finally comes and tells me 'Just go its no use arguing with me bcos there is nothing I can do'. Why could they not put up signage or atleast make sure that the long line of people waiting to buy were informed that they were only accepting cash? Im actually extremely annoyed at th before waiting so painfully long and then being rude about it afterwards. What a waste of time, waste of my lunch.
