The best advice I can give is to truly be helpful. Find ways that you can help the customer and make their experience more enjoyable.
In my full time position at Snorkel-Mart, our customers are ordering snorkeling gear to take along with them on a vacation, or trip to a beautiful island or beach. It’s hard to find the right size gear, differentiate between different pieces of snorkeling gear, and make sure to get the best price. It’s my advice to listen very well to what the customer is saying, ask lots of questions, and then recommend what you would do if you were in their shoes.
Lastly, I would say that you should completely focus on the job that you were hired to do. At one of my previous jobs I was so consumed by what the company had in store for me so I could get a promotion. I was trying so hard to get noticed and show people what I was capable of. When focusing on that, I ended up giving mediocre service. When I realized that I was doing this, I made it my goal to focus completely on the customer and making sure that I matched them up perfectly with what they were expecting and went above and beyond in recommending solutions for them. When focusing 100% on listening to the customer and being very helpful really made a big difference in how enjoyable it was to come to work.
