Signature is often declined at nightclubs, unfortunately. So I keep my costs under 30 GBP. I think the reason for declining signature at nightclubs is the fast paced sales of drinks, so they don't have to deal with cards that don't fit the norm.
Had that happen as well. But if I have my passport on me, I have a pen, but I try to leave it at the hotel for safety reasons (of passport, not mine).
