we are being invaded!

There are a lot of people here in Melbourne that speak another lang.Ofcourse they speak English,that is when you want something or ask'em something but as soon as you turn around they're speaking their own lang.For instance today I waited for some one in the hairdresser,now when she went in she told the woman that works their,why she was there and what for so the woman took her.Soon as she sat down in that chair then they all started talking Spanish to each other.Their where 3 hairdressers plus 3 other women sitting,all getting worked on all speaking Spanish then more women came in and they spoke Spanish....(at least I think it was Spanish)...Even talking on the phone!I tell you,my head was just spinning!!
