I tried using my coupon from the app for a free Happy Meal. It's national youth day, so b1g1 on Happy Meals. I didn't order the right meal evidently, got the mighty kids instead of basic, so I was charged full price. Instead of being told I ordered wrong and allowing me to change it. Employee had an attitude and didn't even give me my full order or straws for my drinks. All because I questioned why they would charge me instead of informing my coupon was invalid or allowing me to change my order. User's recommendation: Double check your coupon with the cashier before ordering.
