Bad treatment, teach your staff that voucher is another form of payment not free as they think

I'm writing to express my disappointment with the service I've experienced at your Centurion Mall and Mall of Africa locations when paying with vouchers. As a regular customer and fan of your donuts, I believe all customers deserve respectful treatment, regardless of their payment method. Whether using a voucher or cash, we're all using a form of currency and expect a consistent level of service.

Unfortunately, I've felt a noticeable difference in attitude from your cashiers when using vouchers, almost as if it's perceived as a "free" treat. I've also overheard discussions about customers using vouchers in a less-than-positive light, which concerns me about the training your staff receive.

I want to emphasize that if vouchers aren't a preferred payment method, I suggest removing them as an option altogether rather than treating customers who use them differently. Every customer deserves warmth and professionalism, and feeling like "trash" isn't what I expect from a business I support.
