Most restaurants keep reservations in a $2.75 spiral notebook.
I doubt an online reservation calendar would be $10k for a single restaurant, but still…the only profit is marginal: the people who eat there who would have without the online calendar, and I doubt it would recoup the costs in a quarter or two. Especially considering that the wealth gap and tech gap mean that the number of people who want to schedule online is inversely related to the people who can afford to eat out a lot.
The DNC is working for their rich donors and doing a pretty decent job for them. They shouldn’t act so surprised that people who aren’t benefiting from the economy don’t come out to support them.
