Who is in the Right, Citibike Employee or Me??

The other day I was on my way to do some errands when I saw a great point opportunity in the Manhattan area. The drop of spot was a major hub that needed bikes for after work riders, so was awarding 12 points.  So I went out of my way and dropped my bike off there scoring a good point combo. After docking I saw they were still awarding 12 points for drop off. A quarter mile away, a station was awarding high points to pick up. It was a nice night so I decided to do the combo to get some great points.  When I got back to the major CB hub, I docked the bike. All of a sudden an irate Citibike employee working as a concierge came up to me and said if I continued to do BikeAngels there he was going to suspend my BikeAngels membership. I was taken back, since this is the first time in 5ish years doing BA, that a concierge ever approached me like this, they have always been thankful for the help. The employee then went on to say that there were other BikeAngels dropping off bikes making his job hard. I said that I was only going by the points posted and though I was helping. He continued to get nasty, and I told him to take it up with Citibike if the point system is not reflecting a true supply/demand disruption that needs correction. Plus I told him he could have just asked me nicely instead of approaching in a belligerent way, I was not trying to cause him extra work. I then did my errands.

Anyway has this ever happened to others? Thanks!
