What is something useful a roaster could give to a coffee shop?

[fivepointroaster]

Hi all! I am a small roaster and I'm trying to build my accounts in cafes. I want to provide the shop a small "thank you" if they become clients that would be 1) useful to the shop 2) promote our brand alongside theirs. For example, another roaster I've seen gives open/ closed signs to the shop to hang on their door. They are branded with the roaster (fulfilling the promotional part) and it's a cheap but useful item for the shop to have.

I've thought about mugs or sleeves but they're too expensive (and a recurring expense). And table cards don't really help the cafe at all. What else would be useful to the cafe and have high customer visibility?

Thanks for the advice!
