Of course they do.
The reason you don't encounter many Orthodox Jewish wearing a distinct traditional garb in many everyday situations, is that first, they are a very small portion of the population.
If you live in an area where there are many Jews, many of them work those everyday jobs in their neighborhoods.
Also they may be drawn towards jobs where appearance doesn't matter that much, so they won't be so visible interacting with customers etc. - so you won't see them, they might be working inside an office. Being stared at while doing your job every day gets old fast.
Also you will be hard pressed to tell an Orthodox Jewish woman working a regular job from a gentile woman dressed in office clothing. In some Orthodox Jewish communities, many women work supporting their families, allowing their husbands to pursue more spiritual professions that are not big on income (rabbis, jewish scholars, jewish studies teachers...).
And finally, not all Orthodox Jews look different. Those who differ in dress are usually more insular, preferring to work within their communities. Those who are Modern Orthodox look like regular folks and work regular jobs. You might not know that the baseball cap has a kipa underneath...some men might not even wear a kipa in an office environment. And a man doesn't have to wear a beard and have long curly sidelocks, or to let his tzitzit swing outside, to be an Orthodox Jew.
