Running a small business is having lots of loose ends to manage by only one person. The restaurateur spends all day doing kitchen and front of house, closes the restaurant, and then looks forward to bookkeeping. They’re responsible for HR, payroll, scheduling, and marketing. They have to supervise repairs to the physical plant. Often, they forget which service you need to update to change the hours, they don’t realize that Yelp has changed their phone number to a GrubHub number until they’ve been receiving advertising bills, and even then maybe aren’t sure why it’s so expensive, etc. There are hundreds of companies trying to take advantage of you depending on the limited time you have to dedicate to everything. Why do I get so many “ads” that look like invoices? It must be an effective technique.
