Apparently, the shirt-wearer assumed that the gym owner is a Jew because when told that his membership is no longer active, he complains to him saying “You know there are no gyms left in Gaza because you people bombed them all.” What he didn’t realize was that the owner of the gym is an Iranian. Police had to be called to get the Jew-hater out.
