Not serving alcohol at the Smash Club was the stupidest idea ever
That basically closed down the Smash Club to anyone out of high school (why would a college kid go to a club where they couldn't get beer?) so therefore Jesse's target audience was basically children in Middle School and High School (Parents aren't going to allow Elementary Kids to go to a club after school unsupervised). This means the earliest he could open up was 4PM. Now most kids have after school activities after school (sports, clubs, jobs) so that shuts down a huge demographic and on top of that most parents are going to want their kids to do their HW after school so that shuts down another huge demographic. No matter what Jesse is going to have to close up around 8PM because the kids are going to have to go home for dinner. Not to mention the fact that Middle and High School kids typically don't have any money!!!
In reality the Smash Club would have gone out of business inside of a month, another really stupid Full house moment.
