I went to the kiosk to rent 2 umbrellas, a super rude girl was standing in the booth staring at me for 30 seconds without asking if I needed any help, I took 1 step forward and asked "where I can get umbrellas" she pantomimed with her finger without saying anything (meaning here). I paid 40$ for 2 umbrellas and another guy came with me to give me umbrellas, I asked him if he could bring umbrellas a little further to where we were sitting he said he couldn't!!
I went back to the kiosk told the girl that I didn't know you can't move umbrellas, she replied rudely: I told you but she actually never had..I asked for a refund and she refused to do by saying it's written on back of your receipt "final sales" again I added "you gave me this receipt after you charged me and didn't tell me anything about no refunds before that" she replied "it is what it is"
I insisted to see or talk to her manager and she started whispering something and whining...
After few minutes ignoring me and pretending to help some other customers she said that her manager would be there in 30 minutes.
I even told her that her behavior was not appropriate for a face to face interaction, she replied proudly "everyone says that to me"!!!!!!!

Impoliteness and rudeness of this particular employee is a reason that I'm never going to get a bottle of water from boucher brothers even if I'm dying from thirst.
After 5 times refering to the kiosk she finally told me that she gave the refund which was an absolute lie.. I never got my 40 $ back and most importantly they sold me some service which they never gave it to me.
I'm writing this 10 days after the incident and the money hasn't come back to my account yet and I'm sure it won't.

Don't waste your money there, since at wallgreens you can get a basic beach umbrella for 14$ and it's good enough to enjoy your day at the beach and don't ruin your beautiful sunny day by arguing with the most rude, arrogant and unprofessional liar employee.
It's not good to judge a company by a bad hire but this behavior and interaction was bad enough to do so.
I would give zero stars or even negative stars if it gave me the option for!!
