When your job involves interacting with and/or providing service to other people, it doesn't really matter how they act, you always have to be nice to them because it's your job on the line. With your job comes expectations, one of which is to do what is needed to ensure that your customers are happy and satisfied. If you encounter a douchebag customer, sure you might be "in the right" by throwing them out, but in all likelihood that's going to mean jack **** to your employer once he/she finds a customer complaint sheet on his/her desk. It won't matter to him/her if you say "but the customer was 'blah blah blah.'" If your actions as an employee make the store/restaurant/whateer look bad, guess what? You get replaced. Part time employees are a dime a dozen. If customers complain about the first one, then they get fired and they bring on the second one. So you have to ask yourself, is being "morally right" worth losing your job and becoming unemployed?
If you want to ensure that you don't get in **** because of a secret shopper all you need to do is the following:
- always make sure that you treat your customers with respect, even if they're douchebags
- always make sure you do your job properly, following the procedures/protocols you were taught during your training time
- always make sure that you treat your customers with respect, even if they're douchebags
- always make sure that you treat your co-workers with respect, even if they're douchebags
- always make sure that you treat your customers with respect, even if they're douchebags.
Finally, most importantly, and above all else...
- always make sure that you treat your customers with respect, even if they're douchebags.
Is it harsh for you as the worker to have to do all this? Yes. Is it still all expected of you? Yes. Is your job on the line every time you decide to ignore one of these? Yes. Is it unfair to the worker that you can't treat customers like **** if they treat you like **** first? Yes, but it doesn't matter. Grow a pair and man up if you want to keep your job. Welcome to the world of work.
