Courteous and Efficient

I've been here for glasses and contacts and found them courteous and efficient. But what made them superheroes is when I panicked after getting contacts. I thought I couldn't get a contact lens out and they said to come in even though they were on their way out. They spent 20 minutes with me looking for a contact lens that wasn't there. They sent me on my way with a new contact told me to come back if there was any discomfort.
