There’s a trend with delivery apps where they add restaurants to their service listing even if the restaurant hasn’t consented. The apps will configure the menus using copies that have been posted online (sometimes out of date with products the restaurant no longer offers) and use their delivery drivers as middle men to place the orders manually. If you are a large restaurant and the apps are going to list you regardless, there is incentive to reach an agreement and control offerings rather than deal with the customer service impact of misattributed third party issues. Some restaurants maintain their own independent delivery services even when apps force their way into being a competing delivery option.
