SMASH,
I agree completely. Pro shop, while not inferring a professional bowler, SHOULD infer a professional salesman who is experienced in his field and portrays exemplary skill, aptitude, and attitude in the field of selling, drilling, and repairing bowling equipment.
Back when I worked in a shop ( YEARS ago now ), we stood behind our work and the quality thereof. If we worked on a ball, it was right or we would make it right. And, if the plugs cracked out, regardless of timeframe, we would re-plug AT NO COST to the customer.
Too many people just out there trying to make as fast a buck as possible, turning out crap with little or no pride in their workmanship.
