Tire discounters can’t align my Dart.

I would take it back and ask for an alignment check. Have the Manager or person in charge witness it and get a print out.
Anyone who knows how to use the equipment can do that even if they don't know how to adjust anything.
Skosh charts and such have nothing to do with an alignment pull. That would just be either extreme camber difference from side to side or more likely caster difference.
The print out will tell the tale. If it is a chain store next step is corporate. You will get a refund.
Always best to find a company that aligns cars regularly not just a sideline. Bear Frame an Wheel centers comes to mind. There are others.
Find a place that aligns SUV's and trucks. They still require complete camber, caster, toe alignments unlike the cars that generally have strut suspensions and rarely get more than a toe adjustment.
Remember that the people who did those alignments "back in the day" are now either dead or too old to work on cars, so don't expect to find an old timer to do it.
