Hi everyone ! New student pilot here! I have 12 hours logged so far at time of this post. Anyways. So Sunday morning at 10am i arrived at the KTMB and met with my CFI and we flew around till about 11:40 did a bunch of touch and goes and worked on my flight patterns. On our last full stop we landed perfect and i was taxing back to my CFI's hanger and pulled off the taxiway and noticed 4 black suvs "new caddys" lined up in a row in the hanger next to my CFI's hanger. His is the last hanger in the strip on the left. So i slowed down as much as i could, because the suv's where taking up so much space in between the rows of hangers and there was a bunch of big guys in black suits " it was super hot and humid not a good thing to wear" standing all around so i barely squeeze by in our 172. On the right side i am about a 1 foot from the opposite hangar and on the left i was about 3 feet from the head one of the security people standing around. I as drive by he gives us a bad look and did not even move. So i reach the end of the hangar road and i put the brakes on and i notice one of big security guys is on the right side behind the wing. My CFI tells me finish the shutdown procedure and as he is getting out of the plane the big security guy yells at my CFI to stay in the plane. My CFI tells him excuse me? and to get the f*** away from his airplane and then my CFI walks inside his hanger. Wile my CFI is inside and i am in the process of finishing my shutdown. Mind you i am in the middle of revving the engine to 1700 to check the magnetos i see the security guy come over to my side and tells me to get out of the plane. I yelled at him to stay back until i shut the plane down and its not safe to be standing by the aircraft and are you stupid get back!! I revved it down real quick and shut it off. So then my CFI comes out of the hanger now with a bat telling them to get away from his hanger and his plane and to leave his student alone. Then a guys comes running over who turns out to be a grant cardone " from what i am told after" and starts to apologies to my CFI. My CFI tells him that his people are stupid to come near a running aircraft. The hanger manager of signature also shows up now. My CFI must have called him and he ended up apologizing to my CFI as well and said how unsafe the security teams actions where and how he would address it. I had to post this, I am new the piloting world but this was crazy. I mean who runs up to a running plane? Do i need to yell clear all the time or something? What a day. P.S " yea i know my grammar sucks"
