It is not certain what their field of business is but judging by their slogan "get some in your tanks today" on the calender and it being placed in a garage, it is assumed STD is a fuel company. They could also be a brewery as their logo is similar to that of Budweiser, so their slogan may be referring to the consumption of alcohol.
- 'STD' is a clear reference to 'sexually transmitted disease'.
- There are at least two calendars in the Doherty Garage; one in the main service area on the office exterior wall and the other inside the office.
- The calendar is open on the month of January and uses the Sunday-Saturday week format. The first day of the month is shown to be Thursday, which was the first day of 1987 so the garage must have been abandoned for at least five years.
- The company shares its name with STD Contractors in Grand Theft Auto V and the STD (Sentinel Tuning Division) that appears in the Sentinel decals. It is not known if all these are related.
