At my last shop, we were fairly busy on the average day with both calls and walk-ins. College town...
...but a rainy day just about guaranteed we wouldn't see many walk-ins OR get very many calls. Don't know why that was. But it was a noticeable effect on every rainy day.
I can understand older people staying in when it rained, but the college kids are young enough they aren't afraid of the weather? And why would our *calls* decrease too, it's beyond me. Perhaps people were afraid the call would lead to them having to go out in the rain.
Didn't stop our business clients though... the show must go on!
