I will say, formerly working in a "fast food" situation ie. Starbucks, it is VERY easy to go auto pilot while making things. Like someone comes in and says I want a Venti with whip Caramel Macchiato. They don't normally get whip, just foam and caramel. Then the person looks at me and says, Is there whip? I remember and have to top it off. Or frequently the order gets processed, I would start the drink and THEN I hear, oh, could you make that nonfat, or sugar free or decaf.
It's never a problem to have to change orders and employees who work in fast food business or restaurant situations SHOULD be able to either change on the fly or accept that they either A. screwed up the order, or B. the person ordered wrong but it's still going to be your fault. Just say "Oh I'm sorry!" Mean it, and remake it the correct way. If the customer is still upset, offer some kind of repair to them such as a coupon or a "Sorry for such a bad experience, the next one is on the house".
If you have gone to the assistant manager or manager and nothing has been done about a repeat bad performance from their employees, ask for the district manager's contact information. THIS I would hope, solve those issues. Especially (from reading the first poster), if these TB/KFCs are relatively close to one another, they are probably in the same district, ie, same district manager. Tell them hey I had a good experience here, what is happening in your other store for it to be so bad?
Finally, I've been given written orders from both deaf customers and hearing customers (coworker getting the order for someone else). It is always written clearly and cleanly. If it is not legible, the employee should ask for god's sake! It would probably make things go quicker asking for clarification than making it wrong and having to remake it! Or for instance, we had many people ask for sugar free and nonfat. If the drink typically comes with whip, I would ask, do you still want the whip on that? Most say no! It's not that hard to communicate or write!
There are unfortunately lazy employees in these businesses that give good ones a bad name. But truly, try going to the district manager and if you don't get that information or wrong information. Go online and file a complaint!
