A customer slipping on your floor, a visitor at the worksite and an allegation about finished work are three very different problems, and companies price them differently.
That variation works in your favour once you are talking to more than one of them. Describe the services you perform and where you perform them, then ask which parts of each proposed policy address those operations and which exclusions deserve a closer look. Shop owners in nearby towns, such as Havana's storefronts and offices, get the same comparison.
