Almost 10 years ago, when I left my bank job to go on maternity leave, I got a big bunch of flowers and (most probably, but I don't remember very well) a card. After I had been kept working at the front counter , serving a huge queue of customers until the last minute - I was meant to finish at 1 pm as I had an antenatal appointment at 2 pm. At 12:55 I was still working, my manager just came and told me "that's you, I will take over and balance your cash, enjoy your maternity leave, hope all goes well, off you go", gave me the flowers (and the card, if there was one) , helped me get my jacket and my bag and two minutes later I was outside the bank, on my way to my antenatal. My colleagues were busy serving the customers so I couldn't even say good bye to them. I have to admit that during my last month of work I did receive a few presents (small gifts, a couple of cards with vouchers) but they were from some customers who I had been dealt with for years by then.
A couple of years later, when I left that job for good (voluntary redundancy) I received again a bunch of flowers and a card, but I didn't really expect anything since during my last couple of weeks there I had been asked to cover a position somewhere else and those people didn't really know me, they just knew I was to be there for 10 days and that's it. They did sign the card though and I am sure that the manager bought the flowers using money from their "office expenses account", but everyone wished me well and there had been cakes and biscuits brought to the office that day. It did feel quite surreal though.
All the best in the new job, OP, and I hope the people you will work with will be friendly and pleasant to work with.
