You never know if someplace is desperate for an employee that can start right away, but if you walk in dressed in shabby jeans, a T Shirt, and flip flops, you will not be considered for that job.
Also treat every single employee that you meet during that first encounter with sincerity and respect. They probably will be asked by the boss for their first impressions. First impressions are the KEY to any eventual employment.
All advice I gave my 3 boys, all but my youngest (15) are currently employed. The other piece of advice I passed along was, in this world there are 2 kinds of people, doers and talkers. Talkers talk because they can’t or won’t do, doer don’t need to talk because they do. Don’t be a talker, be a doer, and you will never lack for a job opportunity. They listened and I have a teenager working in an almost 26% unemployment rate for teens, and a 20 something at the top of his field as a personal trainer in this slow economy. The youngest is having a bit of trouble finding a way to get in the door during this down economy, but he will also prevail after his birthday I have no doubt-(easier at 16 than 15 to find work)
