My most important rule: Leave the business if it smells terrible.
If it smells terrible then most likely the food is terrible. I always break my rule though because it is inconvenient to leave. I stayed and it turns out that the food was terrible. Also I think this Wendy's used to have a cockroach as the profile picture since the location was infested with cockroaches, but I think they took it off lol. Do not go here; trust me.
