is it the first time it is happening with him?? did he do that in the past as well, i mean has he always been the way he is now??

if it is the first time..and been good before..may be he is trying to make the project the BEST looking one and most successfull..in that case i mean things change quite often..BUSINESS AT THE THOUGHT OF SPEED!!

if it is always been the case...then just dont worry abt him ....take it easy...and wellu have no option othen than doing wht he says ...but you can do something ...talk to him in a very very very polite way so that he does not get offended and kick u back later!!

but be carefull ..be polite and honest..

cheers..just my opinion ..may be i am crazyy
