What five details suggest Mr. Calloway's band's success in chapters 13-16 of Bud, Not Buddy?

There are several details that lead the reader to assume that Mr. Calloway and his band are very successful.  First of all, they can afford to eat at the Sweet Pea, the "best restaurant in Grand Rapids" (Ch. 13).  Also, they eat there so regularly, and are so well known, that there is a table reserved just for the band, even though there are a number of other people waiting to eat (Ch. 14).  A third detail that evidences the success of the band is the fact that being able to be included in it is enviable and competitive.  Thug, who is trying to "stay in this band longer than the last three drummers did", calls the slot "the best drumming gig in the state" (Ch. 13).

The fourth and fifth details that point to the success of the band have to do with the material things the members are privileged to have.  When Bud meets Miss Thomas and shakes her hand, he immediately notices that "there were about nine diamond rings on just her right hand" (Ch. 14).  Also, Herman Calloway himself is apparently the owner of a very spacious dwelling, the "Grand Calloway Station", a house with two stories, several rooms, and people going "in and out...at...many hours of the day and night" (Ch. 15). 

A final indication of the band's prosperity is that, even during the Great Depression, it has a schedule that is "pretty heavy for the next couple of months" (Ch. 16).  Clearly, Herman Calloway's band is doing very well!

The reader is led to believe that the band is successful because of many elements the author weaves into the plot. Right from the beginning of the story, the flyer Bud carries around is described in detail. It contains words that would lead someone to think the band was a success. The flyer indicated that the band was coming from a limited standing room only (SRO) engagement in New York City. They were referred to as masters of jazz on the flyer.

When Bud finally finds Mr. Calloway, he finds that he has a luxurious car. He also has a band of several members and they appear to be practicing and setting up on a stage at a venue.

The band members all travel together to a restaurant to eat. The meal is large and they all appear to eat well. The lead singer of the band is described as being well dressed and having a good deal of jewelry.

In talking with Bud, the band members explain that in the future they have many long car rides all over Michigan to performances that are booked. They obviously are in demand.
