- when we deliver the rental machines, the bigger ones can not go up a flight of stairs. can anyone help me out in this regard? what i usually do is ask the other person on the phone if he can recall anyone who mentioned to him that they needed to ship something!!! what is the typical permanent salary of a service designer? compared to other types of equipment and items that are used for physical fitness exercises, pull-up bands are the best. really, the writing’s on the wall, have the grace to step down.
