new job...

so tell me why my new job is putting me into my first day shift with only one hour of training and on the busiest day of the week...like what the heck am I supposed to do if someone breaks their ankle (I work at a trampoline park btdubs) like what do you mean I have to work around hundreds of children on my FIRST day, and online training. I might cry. my shirt is also so small and I don't think I will be able to wear it for 4 hours straight before wanting to rip it off my body in the middle of the place. anyways how is everyone ? :P
