From the HS Brands website, "HS Brands International is the culmination of 15 years of change, growth and success. In late 2006 Thomas Mills Jr., CEO of Service Sleuth and Michael Mershimer, CEO of The Mershimer Group, Inc. agreed upon a merger of Service Sleuth Mystery Shopping Services and The Mershimer Group, Inc, a leading Loss Prevention Consulting firm to create HS Brands."
I have shopped a little with Service Sleuth, but am not sure what information, or comments, you're wanting.
