I think maybe sending a brief note explaing what happened to the attention of the owner or manager. Also ask that you receive some kind of response so that "you" know the owner/manager is aware of what happened, just in case the "employee" intercepts the note. If you receive no response I would look for another place to spend my hard earned money. I have had mistakes happen at my LQS and they always correct them immediately , with smiles and apologies . Everyone makes mistakes it is how you handle them that is more important :wink:
