TLDR: no car wash, general service, mostly prepackaged foods, connected to a McDonalds
This Terrible's reflects the par-standard experience you will receive at many Chevron locations. While the standard clerk attempts to provide expedient service, the lines for check-out May reflect the need for additional staffing. At this location, you can select your own fountain drink with their updated Coca-Cola Freestyle Drink Machine. But even with 100+ drink combinations to choose from, how can you compete with the $1 drink for any size at the adjoining McDonald's? Is the $0.49 worth your time? Only time will tell. I foresee all Terrible's locations to be updating to this dispenser-type system.
Restrooms aren't that bad. For the afternoon, it looked pretty maintained. Needless to say, it's right near the freeway and connected a McDonald's; I wouldn't be dissuaded in stopping by soon.
