Actually it is from mostly harmless, after arthur gets rescued by ford, and they ride the perfectly normal beast out of the village and to the land of the king (I.E elvis(on an alien world, go figure)) and ford sees a nice ship outside the bar of the king he wants to buy, so he starts a tab at the bar, goes to the lead singer who owns the ship, and gives him a large amount of cash from his hitchikers card, he then names the figure to arthur, who asks what it could buy, ford runs a few calculations and says it would buy switzerland.

the bit in milliways the bar bill was never mentiond only that he signed it under "hotblack" and then he gets a radio message later involving a bar bill and his exicutioner
