Coffee grounds (Allerton Bywater WF10)

Hello Freeglers. Any cafe/ coffee shop owners/managers that would be happy to provide me with coffee grounds for my compost pile please? I have an allotment and coffee grounds are great for composting. A steady- ish supply would be awesome! I am on the Wakefield/Leeds boundary so somewhere not to far to travel to would be great. However, I am willing to travel for it. Thank you.
