I tend to agree with anotherhiggins on this one... sounds like the guy's personal beef.
"Please don't hesitate to contact me..." is certainly different than his suggestion of "Please call me."
When I see "Please call me", I think that there is something that has been omitted for some reason, and that I *need* to contact that person by phone.
In my trainings, the last slide usually includes my extension, with me saying "Please don't hesitate to call if you are having issus", etc.... making a statement that calling me is welcomed, but their choice.
As I have said in the past, the focus should be on the customer; both internal and external. My external customers are the ones who pay the bills. My internal customers are every single person in my company who uses a computer (which means every person in my building.)
I keep a container of gumballs on the table in my office (I got that idea from Posner's "The Leadership Challenge", from a manager who had a popcorn machine in his office). This way, people can "just stop by" for a gumball, which gives me the opportunity to say "Oh, hey, glad you stopped by. How's that new mouse working for you?" etc.
Sure... gumballs cost me out of my own pocket ($24 to $38 a case)... and last about 2 months... *BUT* for the amount of additional customer contact I get, and the general feel of "my door is always open", it's certainly worth it.
Just my 2¢
