    I ordered a 6 inch to pick up at lunch 12pm. I submitted the order around 10:30am when I got there my 6 inch was ready but it was cold and hard. I ordered it toasted. I didn’t think anything of it, when I opened it to eat it it was cold and hard like when you leave a toasted bread out for too long. I’m assuming they made my order when it was ordered at 10:30 am. I was so disappointed I had to eat it with out the bread.

    I ordered using the app. I asked for extra mayo, mustard, oil, vinegar, bell peppers. The meat was only to one side, no extra mayo/mustard/oil/vinegar in sight. I had to open the sandwich up and rearrange everything. I also added mayo, vinegar, and oil. I’ll just stick to JJ’s

    Rewards member and frequent Subway customer. After purchasing a full-priced footlong, I asked for a cup only to get ice. I was told the store ran out of small cups. Fine. What wasn’t fine was being refused any other cup unless I paid, despite other cups clearly being available behind the counter. I explained I didn’t want a drink and that this situation existed solely because the store ran out of its own supplies. The “solution” offered was that I leave and bring back my own personal cup to get ice. Asking a paying customer to leave the store and return with outside items just to avoid providing a cup that costs a few cents is absurd. This had nothing to do with policy or cost and everything to do with inflexibility and poor judgment. The only impressionable customer in this interaction was me, and the impression left was that customer loyalty and basic courtesy were not valued. Turning something this minor into an issue was completely unnecessary and reflects poorly on how this location handles customers.

    This is my favorite Subway in Fontana. Always great service and friendly workers. They make great non-skimpy sandwiches too!
