On THREE different occasions we were harassed by male passers-by

Was on a date with a girl, weather was nice so we sat outside at a bar in Wedding ( Thursday night). As we chatted, on THREE different occasions we were harassed by male passers-by. 1st: guy stopped and made puking sounds at us. 2nd: guy with buddies comes behind me, slams table, shouts in my ear to scare me. shaken, i move to sit next to date to keep eye on street. 3rd: group passing tries talking to us. we ignore them, so they make racist comments at me (I look Asian, ironically am not).
