Pain From Rising Costs

I am feeling the pain from rising costs.
I went to the market on Sunday.
1) The price of a plate of plain bee-hoon went up from seventy cents to eighty cents. The amount of bee-hoon served remained the same if not slightly lesser.
2) Eight pieces of "yong tou fu" used to cost $1 and now is seven pieces for $1. The fish paste in them seemed reduced.
3) The price of freshly served roti prata went up from sixty cents to seventy cents. The size of the prata has shrunked.

My salary: remains the same!
