Secret Shopper

This business has a coupon ad for a free chicken lo mein or fried if you purchase 30$ worth of food. Which I bought and paid for 40$ worth of Chinese food from this establishment earlier. The elder lady and pre teen teenager declined the coupon and didn’t want to work or give me my free entree. Which makes absolutely no sense at all considering I am supporting your business. They told me to use it next time when I place order. Wow and at a loss of words. Poor management and extremely poor business ethics.
