Couple of ideas of what you can do to prevent being in such a tactical disadvantage next time. These aren't solutions but they could help. Could also make things worse in some situations.
1) Keep "emergency food & water" in your car or in your office for that matter. Having a 72 hour kit in your car makes good sense, and if your in Kali I would think earth quake kit at the office makes sense also.
Power bars, dried fruit, nuts, and/or gorp are good choices and probably better for you than a gut bomb
You can also keep a reserve supply of "instant meals" at home that you can just throw in microwaze.
Think about Lions and other predators, don't they stake out water holes and such to make "hunting" easier? If this is the only food joint open late in the area then you can be sure all the local goblins are aware of the fact. Or in other words it is a know danger area.
2) You could add spot lights to your car, like police squad car, you would want the ones mounted on car not handheld things. You can use these to blind goblins from front or side just like a cop does with a stop. You could also add high intensity lights on front and/or rear bumper [or corners of bumper, etc] pre aimed and all wired to a panic switch.
You can use lights to provide concealment at night.
Can also add PA system or loud [air] horn, though you might be a redneck
If you have a 4x4 and have an air compressor easy enough to add air horn.
