Tried to use a Free sandwich coupon at my local burger king (Danforth and Victoria Park, Toronto, Ontario, Canada) on Sept. 10, 2009. Not only did the employee refuse to accept the coupon, she tried to charge me $11.61 for a whopper combo. Usual price for combo is $7.00.Not only did I leave without any food, (McD's close by) Bk lost a customer. When burger king runs an advertising campaign that includes coupons for free food that they will not honor, they lie. That's the biggest whopper of all. read full review »
