First Job

It was Mark’s first job as an apprentice. His ride had left earlier, so Mark wandered out to the parking lot to see if anybody would give him a ride to town.
Sam walked up to him and said:
“You need a ride into town?”
“Well, yes I do.”
“I’ll give you a ride, C’mon.”
Half way into town Sam turns to young Mark and asks;
“If I hadn’t picked you up how would you have gotten into town?”
“I guess I would had to phone for a taxi.”
“How much would a taxi have cost?”
“Oh about $10.00”
“I’ll take $5.00”
