What about wearing a work tshirt that says: I'm not deaf, I just have selective hearing." - might make the most hardened customers loosen up and find you non threatening. It's something I had thought about recently, too. I think I'll get a tshirt printed.
Think about how you might make it fun and exciting for the customers to talk with you.. especially in a field of business. You can't wait for 'em.. just take the initative and grab 'em in the balls or the boobs
Ha ha, I have a tshirt that says:
"Keep on talking, I love watching your lips moving."
At my workplace, I have to deal with a lot of hearing people, though it is a bit different because they KNOW that I am deaf. Still, there are some people who don't get a clue at all that they need to write with me. The morning supervisor keeps on talking and talking, and when I don't know the topic, I find it hard to follow her. Sometimes I just give up and nod, then ask someone else. You would think that the supervisor would want to make sure that all of her employees understood everything. Not always in her case. However, the night supervisor is wonderful and I really like him. He can tell if I didn't understand him and will write down whatever he said.
I just try my best and smile, and sign "thank you" to everyone. It seems to be quite contagious cos everyone is thanking me now, he he he...
I remember when I worked as a special orders clerk, my contact with customers was through my "secretary" but sometimes I was beckoned by the floor staff or my supervisor to come out and help some customers. First thing I did was to explain them that I was deaf, and I am such a poor lipreader so it probably would be better for us to communicate by paper if it was ok with them. I never had problems with customers from that and it was quite positive experience for me (and perhaps the customer, since he/she got his/her books.)
I remember one time, it was like 2 days before Christmas, and our deadline for ordering books before Christmas had expired. The customer was in a total panic, so the floor staff came to get me. When I got to the station, I was a bit afraid the customer would be rude, but when I explained to her, she had no problem at all. I asked her what book she needed, and then I found out that a store had it but it was one hour away. Customer was like she didn't have time to do it, so I offered to go driving to the other store to pick it up for her, and bringing it back in about two hours. The customer was thrilled and could not stop thanking me. I got a thank you card from her later on, telling how happy she was of her experience with me and that she would keep patronising at our store due to our wonderful workers.
I think it is a matter of attitude. Just smile and say "Im sorry I missed that what did you say?" If there is a word you didn't understand, just ask the person to write that one last word or something. Indeed, you will still have some stupid customers, so it wil not be your fault at all but theirs. There is no need in losing sleep over these lowlifes.
