Walgreens review: rude employee

Me and my fiancé were in the Las Vegas Walgreens right near the SLS . Saturday late night Sunday morning . As we walked into store two employees were having a disagreement I believe . The young man in the back was filling water had asked us if we needed anything . We didn't just were stopping by for snacks for the room. out of no where this other employee screams " Shut the F*** up " to the young gentleman that asked us if we needed help . I wanted to interrupt the situation because that was super rude and rude told the guy I was ready to check out . The young gentleman cane around and looked very sad immediately and my fiancée told him that was so rude of them to yell at me like that and he said they were his supervisor! I than told him to contact corporate or I will and now I'm going out my way because Wrong is Wrong ! I than called the next night looking to speak with a manager . This guy named Cody answers and I asked for manager his puts me on hold with music and than comes back and says he is the manger for the night ! I told him I was looking to speak with the general manager and why did he just lie to me place me on hold and than answer back stating he is manager . He said the manger James will be available Monday morning but didn't give a specific time so I called corporate left a voice message and now I'm reaching out on here . people shouldn't treat other people like that . Super sad for that young guy .
