Are you portraying Christ?

I am going to start off by warning you, this is a bit of a rant. If you don't want to deal with that, then please stop reading now. This blog is mainly aimed at two groups of people who my co-workers at Sonic refer to as "church people" and "Johnson kids."
For those of you who don't know I am a carhop at Sonic. For the most part I enjoy my job. However, there are a few things that really bother me. One of the things that bothers me most is how Christians treat those in the restaurant industry. Some of you work in the restaurant business and know exactly what I am talking about. Those of you who don't have probably heard someone say that Sunday afternoons are the worst time to work because people come in after church and don't tip well. I can not express how true I've found this to be, although we also include Wednesday/Sunday nights after youth group in that statement.
(Side note: Sonic carhops make the same wage as waitresses. We depend on you to tip in order to pay our bills, so please be courteous.)
The average American eats fast food twice a week and eats at a sit down restaurant once a week. This gives Christians a great opportunity to witness to people who they might not otherwise come in contact with. However, if the only time I came in contact with Christians was when I am serving them at Sonic, I would have no interest in the Christ that they proclaim.
The two group I mentioned above, "church people" and "Johnson kids" are the ones whom our carhops most dislike serving. Not only do they rarely tip, but quite often they are also rude. (And then some share a gospel tract). It breaks my heart to see this happen. It also makes it difficult to proclaim the name and ways of Christ to those I work with, when they see the actions of other Christians, many who I know and associate with. So this is my plea, next time you get fast food, stop somewhere to eat, or pull into a stall at Sonic remember that you are portraying Christ. Let the people who are serving you see that there is truly something different about you. Your actions may be the only opportunity you have to share the gospel with them.
