Spirit Airlines review: Gate agents at LAS

On Monday Sept 3th on a flight from LAZ to MCO at 9:46pm. The agents David and Dariona. They were extremely unprofessional, careless, not courteous at all. They talked to customers like We were criminals. At few occasions screaming and telling for absolutely no reason at all. I saw David pulling a foreign black man out if the line in a unprofessional manner because the guy had a small bag with brand new shoes that He purchased inside de airport. David yelled at the guys and told Him He need it to put it inside the back pack or leave behind. I had a back pack with a laptop, small. He pull me out again in a very bad way for me to check if my small backpack fits on the personal space. My back was a lot more smaller than the space. Dariona was next to me and I had to ask Her, if it was ok so I can keep going to the gate. She looked at me pissed and just gave me a bad look and scream, keep going. It was uncalled for and embarrassed. People were asking, what's wrong with this two people. They are the one making Spirit look very bad. They should not be working for Spirit. I have a daughter flight attendance w/Spirit. I have a cousin pilot w/Spirit and more family members and friends working for Spirit. I know they were NOT trained to be unprofessional, not courteous and/or careless.
