If I decide to hire a limo service for a party next month, will they need a deposit first?

Yes. The <a href="https://search.un.org/results.php?query=service">service</a>; needs to be sure you will show up (if you don't, they lose hundreds of dollars.) and you do not damage the <a href="https://jetblacktransportation.com/blog/long-distance-limo-hire/">long distance limo hire</a>. Because of this, they require a booking fee and non-refundable <a href="https://www.biggerpockets.com/search?utf8=%E2%9C%93&term=deposit">deposit</a>;.
