Service issues

We eat at this specific McDonalds at least 3-4 times a week.<br> <br> We always use the drive threw and most of the time it is during lunch time.<br> <br> Every time our order is the same: 2 McDouble Small meals. R29.00 x 2 = R58.00<br> <br> The staff members rotate as far as I can understand from the drive threw answering post.<br> <br> Every single time I order the above mentioned meals the person tells me that there is no such meal and that I can only buy a McDouble burger on its own and buy the chips and Coke separately.<br> <br> When I explain that I buy this exact order multiple times per week and that I do it at this specific branch in this exact same drive-threw they ALWAYS revert to telling me that I am mistaken/confused and last week my favourite - crazy.<br> <br> So after all the explaining I eventually get them to look at my slips from previous orders and then, without any difficulty, they change the order.<br> <br> They then continue to ask me to wait in the parking lot for my food because they are very busy. This takes at least 10-15 minutes per occasion, more often than not I have to go in to the shop and ask for my food because they forget to bring it to me.<br> <br> Can someone please explain to me what the problem is?<br>
