The fee's are more favorable to bigger amounts, it's very annoying making smaller transactions.
I have noticed this too for bigger payments. However, ordinarily one would've thought that the recent fork would've ameliorated this issue of high transaction fee charge as well as the backlog of transactions on blockchain. What is the essence of continuous and replicate forks of minute issues like this aren't taken care of. It's now quite discouraging sending small amount of btc across.
That is the main issue related to bitcoin. We can cannot afford to send small amount of bitcoin because of the increasing transaction fee. It is in fact effecting the image of bitcoin, People want to use bitcoin as normal currency but the increasing amount of transaction fee is in fact a hurdle for them to use bitcoin so smoothly for buying small items, for which they have to pay high transaction fee.
