Are kantors in Poland reluctant to exchange Sterling following Brexit?

Hi, I've just joined, travelling to Gdansk for a holiday, I normally exchange money in kantors. However, I've now been warned kantors are reluctant to exchange sterling following Brexit due to large market fluctuations, is this true? I'm looking to exchange @ 2000 sterling, so is it best to cut my losses and change my money before I go? Thanks, Jerry.

You will most certainly get a far better rate in Poland. Kantors are still happy to exchange pounds, but the spread is now slightly wider.
