I am almost exclusively preparing returns with my clients here.. They have their own monitor where they can see their taxes prepared.  There is a good bank that I use, Huntington Bank that used to have tons of free pens for their customers.. I asked them if they had extra pens and they gave me about 100 of these pens.  I have one or two on my desk for my clients to sign.. My supply of desk pens is dwindling due to mostly folks walking out with them or I throw one out here or there if my client "contaminated it" by sneezing or licking their fingers when turning their pages.  I have never said, hey, can you leave that desk pen.. I just let them walk off with it but my pen supply is dwindling and may have to ask the bank for some more.
