I normally don't like to come to places an hour before they close but the guy who helped me was so nice didn't make me feel like a bourbon, I was sad cause they only had barely an pickles left I ask if he can pour the juice on top of my sandwich cause I normally ask for extra pickles and he did! It was so simple but the customer service was great! Thank you!

I work nights, so I wasn’t aware that this location opened at 9am, and when I went, it was only 8:30.
Seeing as it was closed, I headed back towards my truck, but a wonderful nice lady named Gail came out, and opened the store 1/2 hour early for me. She was kind, compassionate, considerate, observant, and amazing while communicating.
I will be recommending, and coming back (after 9am of course).

Weird customer service, the staff does not seem trained as they didn't understand basic orders, and I was served burnt bread that was ultimately inedible. It's clear whoever owns this Subway is incompetent. Take 5 minutes to drive up the road to 120th and go to that Subway instead, avoid this one.

Around 4pm, The older woman who made my sandwiches was very rude. I don't know if she was being sarcastic or if she was slow. I wouldn't come back.
