This has been bothering me for a while

Sometimes I don't like my work because of people like that who don't value it and want me to lower the price of my art... Just like you reading this post, I need to pay my bills and I have expenses too
So stop making comments like that it's very rude and inappropriate
If you don't agree with the price or it's over your budget, don't bother the artist and look for another one that meets your expectations.

You [client] complaining about the prices of my drawings will not make me reduce them just so you can be happy and buy with me
Stop disrespecting other people's work If it's expensive for you, just don't buy it and don't complain
Art is a luxury item so value and respect people's work, if you think you can do better then do it =)

Note :
I'm not generalizing all customers just the troublemakers who love to give trouble like spoiled brats
So far most of the people I've dealt with have been super polite and some of them help me a lot to this day and I'm very grateful for that: as an artist I feel very privileged that most of them have awareness, maturity and a lot of understanding and patience
But unfortunately there is this clueless minority who loves to end our patience and we are forced to remain quiet out of politeness or sometimes when we give a direct answer we are seen as rude, arrogant and stuck-up artists
so if you can't pay don't buy or make unnecessary comments
