I work for a Sysco-like company and deal with accident and injury investigation. Many things could contribute to this issue: new driver, new route, new customer/restaurant, and just trying to do his job. I get that this is extremely annoying, but their routes start at 4am and they try to get it all done before the rest of us hit the road. They try to build better routes, build the pallets more efficiently, but it’s hard to do. Their supervisors are on them about unloading fast, staying on time, and minimizing risk/injury/accident. And unfortunately blocking the street is low on priority if they can do the above. Sorry bro. Give these guys some grace because they work really hard - lifting 5k pounds A DAY 5+ times a week, driving big trucks around a city, and dealing with upset customers.
