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.

Worst service Ive ever experienced anywhere ever. The lady making my sandwich was irritated about doing her job. Rude the entire time and got upset when I asked her to spread the avocado out a little bit instead of just leaving two spoonful's in the middle of the sandwich. I wish there was an option for zero stars! Horrible experience. If you don’t like your job, get a different one. Don’t treat your customers poorly. Will never visit this location again!

Older lady working tonight around 8 pm (didn't have name tag but had hair in ponytail) was super rude and had a horrible attitude. I ordered a BMT and she talked down to me sarcastically asking me if I wanted meat or no meat and kept making me repeat myself. Rudely told me to give detail... Mayo was out and veggies were frozen. Customer service would be zero stars!

This was the absolute worst experience I have ever had visiting a Subway or ANY fast food restaurant. Both of the ladies working, a younger girl and and older lady were the absolute rudest people I have ever encountered. They acted like us coming in to the empty restaurant ruined their whole day. Before we even made it in the door the younger girl yelled "how many sandwiches" then was rude the entire time she was asking us what bread, types of Sandwhiches, cheese, etc. The older lady came out to do toppings and kept saying like "I need more info from you" I literally got lettuce, tomatoes, pickles, and mayo and said thats it. Then she kept asking me if I was done and I had to say yes 4 times before she started wrapping the sandwhich. Then as we were getting drinks, the younger girl came out and was sighing as we were filling our cups. Another car pulled up and she said to the older lady "do you want to take this customer because I don't." I was going to warn the next customer going in. I have never wanted to call 2 women horrible names before but they were miserable rude people who should not be in service jobs ever.
