If it's local why not call in and buy a little something. Your local tackle shop should be more than willing to help, but I'd call in rather than ask on the phone. Just seems a bit rude, but that's my opinion.
I've done this a few times, and the response has been on the whole, very good.
Of course, it's only good manners to reciprocate, and go in and thank them by actually buying a little bit of something!
It is worthwhile if you're off to a venue that's out of your area- and especially good for ticket information- often you'll find that the nearest shop to the venue you're interested in is the one that will sell day tickets or season books. Then you're bound to call in when you get there, and buy your bait as well!
Obviously I'm talking natural venues here, rather than day ticket commercials with tickets on the bank.
