My professional opinion is that PBI is a royal pain in the ass to deal with. Every time we stop there, without fail, we are harassed. No one meets you at the aircraft. You never know whether or not they want you to offload the bags; you offload ten 50 lb suitcases and they say its not necessary and then you don't offload three 5 lb overnight duffel bags on the next trip and they threaten to detain you because you not following procedure. There IS no procedure at PBI. Its a "make the rules as they go" type operation. The baggage carts that are supposed to be outside are always inside because the agents are too lazy to push them 10 feet out the door.
They take every opportunity to flex their muscle by needlessly inspecting our passengers bags, yet they let EVERY other passenger go through unscathed. The TSA isn't even that bad. They ask personal questions that have NO relevance to their duties or national security, and they do it in a manner so that EVERYONE in the building can hear what is going on; does asking my boss if his ex-wife was on the trip with him or why he has three Viagra pills in his bag have ANY relevance to catching drug smugglers?
Avoid CBP at PBI
