often we are asked for reccomendations from previous clients, now i don't mind giving these but i a never sure of best way. previously we have kept rough contact details (full address etc is stored in brain in case the info got into the wrong hands) of customers that have mentioned i could use them before. I then give the details to the custoer and say they are allowed to contact them. To me this seems the most truthful way as the customer then gets to speak with a real person and not see a writte reccomedation which anyone could have written.
however me issue is that i'd feel aweful if i was to give the details to someone, then find out my previous customer didn't want me to, so i'm having to check with everyone before i give the details out.
how do people deal with this? seems a little silly imo as i could easily give the numbers of friends/family, plus i'd only ever chose custoers who are happy, so what's achieved from it?
