Pollo Tropical

After checking all the store doors at 10:45 am. The store was not open. I waited five or ten minutes and final noticed the the drive through was open. As I was ordering my food there at the drive through, I asked to speak to the manager, he happened to be taking my order and I complained about the door not being open for business. He politely apologized for not being open and explained that four of his employees did not show up. He took our order and we ask what can you do for us because of the inconvenience of having to wait so long and using up our break time.
He then rudely said "absolutely nothing".
As a long time loyal customer I was taken aback by his abrasive tone and feel I should have been treated better.
