Maybe I am the one that misunderstood her question but I do not think she was asking about other forms of payment.
I believe she was talking about gifts, you know, something given as a gift not as a payment.
I think the gift depends on the person, like Dee said, her favorite is a snow globe and the is not only because she collects them,
but because her client thought about her enough to remember that she collects them.
There is one very UTR girl (which I have not heard from for well over a year now... hint hint) that collects old keys,
so every time I come across an old or unique looking key, I think of her and grab it.
EDIT: But you can never go wrong with a good Gift Card.
