Google places, negative impact outside of given region?

[_Rade]

Hi all, and thanks in advance for any replies.

Google Places - great for helping nearby searchers find your business. But would signing up have a negative impact on searches outside of your business' region?

For example (fictional): a user in London searches for "IT support" and finds my IT support business based in London. Great. But if a user in Leeds searches for "IT support", would my company's ranking be worse than if I had not used Google Places at all?

Any thoughts would be appreciated.

Regards,
