One hazzard of consulting -- oops

[tn3270]

Am continuing to enjoy being self employed doing contract jobs. I currently have 2 paying gigs going: company A and company B. At both places, I occasionally talk to clients to do tech support, refine requirements, etc. Today while at company B, I made call to a customer and said this is tn3270 calling from company A. Oops. Fortunately, he has a sense of humor. My problem is that I do more client interaction for company A so that is my default phone greeting. Need to start thinking "where am I" when I pick up a phone.
