Clients pick thier moments!

Why is it that every time I leave the damn office for a day putting up with one client, talking branding and design rubbish, that all the others suddenly decide to get in touch after weeks and months say bugger all! 

No you can have aerating tomorrow on half a days notice! No you can't see all 4 projects next week, you only fed back yesterday! Your golden boy left the business, I look after your pathetic little account know and you're not my priority, I have other clients who pay big boy money! I'm right, you're wrong! You came to me because you don't have the answer, or even the right question, so listen to me!
