The numbers of member sellers with 1 or more tables in the other halls are certainly in the numeric majority and I'm sure would not be happy with any tax rules.

I KNOW many would not be happy with paying sales tax. For some, who deliberately don't pay federal or state income tax on their sales, the requirement of making a sales tax return provides a nexus for a federal or state audit of their operations. What may be onerous is not the sales tax requirement, but rather the record-keeping for federal and state income tax when they have to keep a tally of what they paid for the stuff they eventually sell. If they bought a train set at a garage sale and re-sell it at at TCA event, there is income from that transaction.
