It has been a while since any kind of gift came my way from a client and if I never got another one it would not bother me. Cash gifts are nice of course they are but I don't see them as an unspoken bribe to stay longer or get more out of me than I am prepared to give. They get the time booked and no more. None have mentioned extra time because they tipped me an extra £20 or more. If ever a client hinted that he has been generous etc etc it would fall on deaf ears.
Thinking back I can not recall any gift I have not been able to enjoy or use.
Chocs - I eat the lot as am a bit of a chocoholic or offer to share in the booking
Perfume - I use as room spray if not one I love on my skin
Flowers/pot plants - always welcome!
Wine - not always my taste but I can easily take to family so not wasted
Jewellery is a rare gift but I once received a beautiful gold chain and pendant which I wore for years until I broke it.
A regular client knows my interests in books and has bought me one or two over the years but they are purely gifts and nothing more.
One man has been promising me some vegetables from his allotment for ages, am still waiting for them. He won't get any more service/time just because I have a cauliflower and bag of carrots and onions.
