hi @adsactly, what an interesting and funny story. i have two hypothesis that made the security man to be weary of you; one that you are skinny, (no offense if you are) two that you didn't look rich when went to the shopping mall.. (please tell me that my theories checked out. smiles .)
here in Nigeria, i have had such experience at games shopping mall, but not exactly like yours. i bought a gum among other things, but i opened the orbit chewing gum while still shopping for other stuffs , then when i got to the Cheshire to pay, the security guy was looking at me with the assumption that i might have eaten other things before now and not pay for them. it was so embarrassing , the look he gave me that day.
i like the way you reacted , its simply the best, "kill them with kindness". but i would suggest that you intro the "guard" to steemit so that he will be as happy as you are. (lol). nice story sir.
You're theory might check out ;0)
