Sure. I've been involved with a bunch of vendors who exhibit at conferences. Often there is an "oh shit" moment when you unbox the crates and find that the monitor you have is busted. You're missing an audio cable. You really need a 4' 2x4 to fix a collapsed table.

Doesn't really matter, but you could see a need for an "equipment and stuff" on demand in an hour type of service catering to these events.

Similarly, every wedding venue can have an "emergency" service for missing stuff ("Florist flaked? We can put petals to the metal and have them there in an hour!")

These are perhaps more extreme, but I'm sure there are any number of restaurants in your area that don't deliver, but might like to have that capability. One morning last week I went to my local bagel shop to find the manager loading dozens of boxes of bagels into her car (catering for the local school's Teacher Appreciation Day). There is insufficient demand for the bagel shop to have a full time delivery driver, but big catering orders UberRush might really fill a need for them.
