OMG Seafood

I love the food and have eaten there a handful of times, but I can't eat there after my last experience a few months ago. I was in the "to-go" line about three cars back. A lady was outside taking orders. She was pleasant. I paid for my food there. After my order I waited for 10 minutes for the first vehicle to get their food. Then another 10 for the next vehicle to get their food. When I pulled up. I sat there for 15 minute (yes I timed it). No one said anything to me. There were two people learning the new? POS system. After 15 minutes I knocked on the window. Both of them looked over. I waved, and they just waved back and started getting back to the priority of learning the POS system. Finally another worker was walking by and I knocked again. She was pleasant again, and said that the cook just put my food in the fryer and it will be out shortly. I told her to forget about it and just give me my money back. So I sat there for after I placed my order for 35 minutes and they then just started cooking my food. The people are nice, and the food is good, and that's why I didn't give them 1 star. They have to know to update the customer. If they're short staffed that night then say "sir, I'm sorry, but we're short staffed and it will take longer than expected to get your food out." Update the customer, show them that you care, and respect them by your actions, not solely your words. But when a manager is standing right next to the window learning/teaching a new POS system and they can see that I'm upset, and they hear me ask for my money back, but they don't bother coming over and talking to me, or apologizing, shows me a lot about them.
