unfortunently its the way it goes until your level 70 and camp out in Shattrath. I found all the lowbies where the anoying ones, and once spending time in shatt everything changed.
If it buggs you that much just stay seperated in the towns, 1 at ah, repair, bank, the tree out the front, it sucks but its the only way to get stuff done without having to justify yourself all the goddamn time
