So, pretty much, the first sentence is the hook
The main purpose of the transition word in the sentence: "Meanwhile, Jacey waited for the fitting room to become available." is that it connects a series of similar events. Explanation: Meanwhile can be defined as the time before something happens or before something ends, it is another way to say "during this time".
The problems you see: is where is says “won’t eat nothing accept” when it should be “won’t eat anything accept”
ALSO it should be spelled leaves, not leafs.
