A post on Facebook from a local woman appears to show a thumbtack in her sandwich from Wendy’s on La Porte Road in Waterloo. Amanda Forkenbrock Merkes says in her post from that she stopped at the restaurant but did not began eating her sandwich until she reached the Waverly exit. She says she was stuck in her mouth by something in her sandwich. She then found a thumbtack, of which she posted pictures. Merkes says she called the store several times but could not get through until she arrived back home. They informed her at that point she would need to bring the sandwich and the tack along with a receipt back into the store to get a refund and that they would not accept pictures. The Wendy’s store had no comment when reached yesterday.
