I would say yes, include your location in your on page text.
If I am searching for shoe repair I would most likely search "city shoe repair"
If your shoe repair shop does pop up and you have NOTHING about where you are actually located, I might go to the next site that has a location.
And location will just reinforce the location shoe repair that Google has already started on.It also would help if I am out of town and a bit lost, knowing exactly where this show place is without having to go to googlemaps or places or another map site...
Many times I actually use Yelp (Yelp always has address right easy to find, when websites hide their address)
It might not rank your location-shoe repair SERPS that much, but it SHOULD help your buyers conversion...
