About the putting bags on floors of restaurants - I got a purse hook by the brand "Clipa" and it's great, I use it wherever I go, just hook on the table, I NEVER put my bags on the ground unless I'm at home or office where I know it's clean enough, because I put my bags on my bed once I get home and it's just not very hygienic if I set it on the floors of public spaces. Maybe that'll help ease your mind about taking it out? Also lambskin is not that precious, don't worry about people bumping into you, unless they're holding a craft knife in their hand it shouldn't be a problem
