I want to buy a thank you gift for someone who had helped me out in a work situation. I don't know much about her except she is posher than me (not hard!) in an industry that is quite luvvie - think art gallery type job. She is junior-ish so won't have hugely high salary. I was thinking about £50. Flowers too ephemeral and chocolates/biscuits don't seem massively appropriate. What would you send? I don't feel comfortable sending a gift voucher.
Do any of you have daughters this age - late 20s I think? What would they want as a thank you gift that is appropriate to receive from someone in a work situation?
