I recieved a coupon in the mail for $1.00 off ANY THICKBURGER COMBO.I ordered a little thickburger combo and was told that the coupon did not include this combo.Am I missing something? The coupon only said "ANY THICKBURGER COMBO" and made no exclusions for the little thickburger combo.Shouldn't this combo be considered any thickburger combo? Thanks for letting me sound off!
