I agree with Genie. I played in some nursing homes recently and in one an old lady requested "When Irish Eyes are Smiling" every 10 minutes or so. I did play it several times for her! I wasn't annoyed - I truly think she forgot she'd already heard it. Although I pretty much always stifle any annoyance while playing and try to be gracious, I do find it incomprehensible that people don't realize what kind of a venue they're in when they request a song, as in the examples cited above. Or that they just won't figure "Oh well, I'm in an Irish pub, might as well enjoy something different" instead of making faces and getting upset because you don't know a song from the current charts.
