What does the phrase “花钱买气受“mean？ I have this text:  

购物时，售货员的态度很可能会影响人们的情绪，碰到态度差的售货员，你可以不买，再去别的商店看看。 
如果非要在那儿买，可能花钱买气受。  

What does "花钱买气受“ mean please？
花錢 - spending money

買 - to buy

氣受 - reverse of 受氣 - to be ill-treated

together, 花錢買氣受 is roughly "spending money to buy ill-treating"

have fun :)
