The following is what I recall and it may be inaccurate.
Speedmark purchased S&G, each were then acquired by Shop 'n' Check and finally became part of the MFI conglomeration. The principals of Speedmark then broke with MFI and formed Customer Impact. I checked and my last job for them was in 2007, when they were using the Speedmark name.
I partially agree with Flash as to the nit picking. The grocery shops weren't any problem and they were willing to bonus if needed, BUT, their dining shops were a PIMA. It became soooo bad, it was one of the factors that drove me from fine dining shops and I haven't nor will I re-enter that phase of the business. They currently have a job in my area that pays a $15 fee, with a total of $200+ for dinner; I can imagine it also requires one write a report the size of which would bring a blush to the cheeks of Alexandre Dumas.
