You were lucky it was him that took them and not a genuine thief!
Why you would leave your car keys on display in somewhere like a pub is beyond me
it was a small table surrounded by my close friends and the keys were in front of me but my friend has sly hands, there was no way for anybody to get near the table without any of us noticing seeing we were right in the corner.
i dont leave my keys on display unless they are truly safe
