Let me put it words you might understand...
Okay, Mr. CEO, let's try to get this straight. Now, if I walked into your office and started asking you questions about the exact procedure your janitors or your secretaries or security guards used in each particular situation, would YOU be able to answer ME? Yeah, didn't think so.
So why in the world do you expect me--a part-time employee and not even the manager of this place--to know the standard procedures for the concierge, the housekeepers, and the restaurant? 'Splain that to me, eh?
The concierge is also not supposed to be the errand boy for the chef. If the chef would keep track of his inventory and order his supplies on time, I wouldn't end up doing my job and someone elses for hours at a time.
So... would you like me to wipe for you, too?
