Can i sue superstore for following me and my friend the whole time then stopping us outside for a "bag check"?

if it is relevant , i think it might be, i am a mulatto (mix of caucasian and jamaican), and my friend is very fair skinned (caucasian) and we went to Superstore to shop, but the whole time this guy my friend said she knew followed us around the whole store... i didn't believe her, but then i started noticing it too. we got the idea he thought we were stealing, but my friend said she knew this guy and they were friends... so i started to think maybe it was me... so i tell her what i think and ask her if its ok we leave, she says yes that she thinks we should go, so we leave our baskets and my friend goes in the customer service line to speak her mind but its too long and hot and we got stuff to do so we just leave... but after we walk out the door THAT MAN follows us out, starts a convo with my friend abut some girl they knew that likes him then as we were sayin bye he says that he has to perform a random bag check, provides no identification no nothing..we laugh and ask a random what
