*Tanker* Delivered Oil*<br>This property is as bad as the reviews say, tight is an understatement.<br>Despite the facility conditions, all the staff I interacted with was very friendly, professional and as helpful as could be.<br>I parked on the street, walked into the receiving door and let them know I had arrived. Went back to my truck and waited. After they move trailers out of the way, loader came to my truck and had me pull in. He will give instructions on where to park for unloading. They will have multiple tanks unloading various products at the same time so he will coordinate all this chaos and does a great job at it!<br>This is a pump job.<br>They use their hose and my pump.

Disgusting place! They deliberately keep you longer so they can overload you. Be careful.

Small yard for the receiving side<br><br>No bathrooms for men , only women<br><br>Everyone here is kind of rude .<br><br>yard guy was kind of rude when I he asked to put another trailer on the door which now limited the room I had to back , knowing the wheelbase of the truck is too long ( 272in) for the yard I dropped my trailer and requested he put it on the door as a courtesy. All I did was getting yelled at until he finally said ok .<br><br>I wouldn't deliver here again
