Retuning order numerous times

Being in the audit industry, specializing in voluntary audits, I know the importance of supplying good, no brilliant client service. My experience with KFC Lambton has never been brilliant but more often than not acceptable. It usually just takes a couple of times repeating the order before they get it right. Tonight however was the worst yet! Having placed my order, I had to correct the lady numerous times, even asking her to announce over her head set to please make sure the order was correct. I get the receipt, and still wrong, but not wanting to make a scene I accept the absence of my addition. I get to the next window and pick up my order. The cashier is a bit blunt, but I can understand having to work long hours myself. When I get home I open up the food to find that it has been plastered with what seems to be at least week old lettuce and tomato, and the whole package is a complete mess with the sauce having escaped the flimsy box it has been put in. I return only my burger to mr Phillimon, only to get told that he did not hear and I quote: \it's not my fault". I suggest the franchisee invest in some urgent training and maybe some reading lessons as they clearly cannot hear."""
