I have been to Mexico Beach on 3 separate occasions for vacation and have eaten at Killer Seafood at least 2 or 3 times per visit. Their fish tacos are hands down the best I've ever had but I've yet to receive friendly customer service from their employees. They are always busy but are fast with getting guests their food which is great but some friendliness would go a long way. It's like they don't have to be nice because they know people will flock to their establishment regardless. It's definitely the food and not the customer service that keeps me coming back.
