Today a woman got mad at me for saying that she might want to keep her purse with her because this is a public building and anyone can walk in here, and we have had some thefts. She said "I figured that since it said public library!" and insisted that she could see it so it would not be stolen.
I was fuming about this but then an older man came by the desk to say: "I just wanted to say thank you to the library for letting me access so many resources when I was unemployed and giving me something to do when I didn't have anything. This might be the last time you see me because I got a job!"
Good definitely outweighs bad, but seriously, who gets mad when someone tries to prevent their stuff from getting stolen?
