As a church was vital to the health of the community, and as a nearby church was equally important to the continued health of Dupui's business -- Dupui clearly equating congregants with consumers that would partake of his wares -- one needs to ask whether any "shopping" at Dupui's establishment ever transpired on the Lord's Day?  We have already noted that "obligations" on the frontier could be readily cast aside, but what about a regard for the Fourth Commandment?  Would the sanctity of the Sabbath be honored, or would rampant consumerism rear its ugly head to rule the day?

Dupui's ledger tells us that prodigious quantities of rum were sold on Sundays.  Also sold were beaver hats, leather breeches, an old jacket and fine tooth combs.  The most frequent credit-based transaction, somewhat surprisingly, was for "cash".  In this era of barter and trade, cash was still needed for a variety of purposes, such as the payment of rent, for official warrants and other such legal matters, or to compensate workers.  As the area's only cash machine, it becomes important to recognize and credit the Dupui role as a banking institution that served to accommodate its clients' currency needs even on Sundays.
