Kids Foot Locker

I went in to do some shopping for Christmas 12/22/19 8:30am. Asked one young lady to find a size that was not out on display. Young lady was very nice, proceeds to look for size. Meanwhile another young lady behind the register with (blue hair), yells out she should have looked before she asked for help (speaking about me). The young that was helping me let her know the size was not out in display. At this point I didn't want to purchase the Nike hoodie I was looking for. Was able to find the exact hoodie at Macy's.Cashier was very rude to yell that out, thinking I wasn't going to hear her. To even say that is rude, it's your job to assist customers, instead of being on your phone on company time. I shop at Kids Footlocker/Footlocker every 2-3 months, so to be treated that way makes me want to spend my money elsewhere. I really hope someone takes this serious and address the bad customer service experience I received.
