'Solicitors' in this area, on the other hand, are door-to-door salespeople offering a variety of goods and/or services. "No soliciting" is a commonly posted sign in areas where these kinds of salespeople are not wanted.
Yes indeed I was rather bemused to see a "No Soliciting" sign at the entance to a Court House in the USA. Here in Scotland solicitors (lawyers or attorneys) go to court for the express purpose of soliciting their client's case to the judge.
