A sign is so simple & could of saved me the time!

I must say i am VERY UNHAPPY about the following situation!<br> <br> I stopped at Steers in Okavango Road and went through the Drive through as i was hot, bothered and tired after a long day. This was about 17:30, after waiting ten minutes in the queue, i got to the front. I was happy to place my order but then the woman said that the ice cream machine was not working! So i had to sit and wait another 15 minutes to get out the the queue of cars because i could not reverse and came out with nothing! Could they not have put a sign up saying: Sorry no ice cream or something. But no! i had to wait in a queue for no reason what so ever!!!!!! When i could eventually leave i thought lets try the KFC ice cream. I normally only buy Steers as i enjoy your food. So i took a chance and not only was it available but the chocolate sauce was delicious! I have decided i will now be changing to KFC in the future and not waste my time with Steers, i have been a Steers customer for YEARS! But now i will choose another place as i don't have time for a company who doesn't value their clients time seeing as they could not put up a simple sign.!<br> <br> I am hoping to have at least some response to this mail.<br> <br>
