I witnessed something very strange today and I had to share it with you guys

I went to the LV store for a quick visit and just to take a look at some new bags, my boyfriend was waiting outside because he went to get something from the bakery. When I went outside to meet him, he showed me what was going on. A reseller (or his middleman) was sending in "runners" into the LV store to buy as many bags as possible. I just saw how a "runner" was giving the bag to the reseller and they were exchanging money for bag. My boyfriend told me that he went past them before (when he went to the bakery) and had a quick chat with them out of curiosity because the "reseller" has been waiting on a few persons coming out of LV already. He did not confirm it directly but out of the conversation and his behavior my boyfriend could tell that they were trying to buy as man LV bags as possible with different people going inside the LV store just to resell them in the end. (He knows a few people in the sneaker/limited edition reselling business)
When I was inside I saw the "runner" inside and he paid cash, he wanted to buy 3 bags but the SA just let him buy 2 because of a limit. It seemed that the SA already knew that he would pay in cash. LV is out there banning individuals from buying but then THIS happens. What is going on?
