The best/worst times to stop really depend on the particular ABS and the area it's located. You really have to learn through trial and error what times attract a crowd and what times are dead. Even then, you'll find that there are no hard and fast rules that you can absolutely count on. My experience with ABS in more rural settings has been that weekends are much better than weekdays. On the weekend, you get more people around lunchtime (noon), after work (+5pm) and late night (+10pm). During the week, the best time seems to either be around lunchtime or after work (5-7pm).
In the end, my best advice is that if you're horny and want to hit up your local ABS, do it regardless of what time it is. You won't get any action if you never stop. Case in point, I once preplanned a trip to the nearest ABS to visit the gloryholes and it ended up snowing really hard on the day in question. Since I was making a special trip, I braved the poor road conditions and pulled in to find one other car in the parking lot. This actually appealed to me because I didn't like a crowd and preferred to play one-on-one. However, I quickly discovered the car belonged to the clerk working the front desk. Dejected, I finally entered a booth and put some money in the video machine. At least, I thought, I'll watch some porn and rub one out. Before I could even pull it out, I heard a shuffling noise and peered down the dark hallway to see an older man walking towards me. He entered the adjacent booth and shortly thereafter, I was sucking my very first cock. Eventually, I sucked a second cock that day and when I eventually left, the place was fairly crowded. I'm guessing that others had driven by and upon seeing a car in the parking lot, stopped to check things out. If I hadn't stopped, they wouldn't have either.
