Out of curiosity, where are they located? I got (yet another) email for a shop somewhere, without listing the state. I have emailed back to schedulers again and again suggesting they would be more successful if they listed the state, not just the city, since so many city and town names are repeated throughout the country. I have also emailed suggesting that their strategy of "Your zip code starts with a 5. This shop's zip starts with a 4, so therefore it should be possible to get there by noon today" is not the best idea and that listing by state would make more sense.
(For schedulers in the US, I might get a little testy if they don't understand that a $5 bonus will not take someone from Council Bluffs to Dubuque. For folks outside the country, you think they could look on a map and see why someone in Iowa can't make it to Michigan by lunch unless he or she had a private jet.)
