No work will make feel like a slave like working in advertising agencies, it’s really frustrating cause majority of clients are either dump or assholes, and most of the time both 
so no more advertising agencies for me cause you will have to do stupid stuff just because the greatest client ever asked for it.
Once I had an idea of a funny cartoon that will represent our pathetic situation with our beloved clients, then I asked a friend of mine, Mohammed AlShaer, to draw it, he did and he made the client looks like me 
here is the conversation between the client and the CS:
Client: Listen I’m having a baby girl, I want your copywriter to come up with at least 14 fluffy cute names for a girl.
Client Servicing: Yaay, sure we will!
OMG!! That is SOOOOOOOOOOOOOO True….
I am currentoly working in an ad agency and the clients are driving me mad…all they do is brief us with something like: “i want a creative catchy ad, slogan, or name for a new product”….and then when give them A LOT of options; they say: “no we don’t like them, we want it simple, yet catchy, and also creative” (AHHHHHHHHHHHHHHHHHHHHHHHHHHH) They are giving me the hardest time ever….they don’t ealborate at all (cuz frankly they don’t knwo what the hell they want)…and some of them are just merely stupid, ignorant, and RUDE!!!!
