Simply being kind and saying thank you and please while being served is not only right but can actually get you some free stuff =D win win if you ask me! Imagine that? Tell someone working hard "Can I get xyz please" and then say thanks and see they hand you some employee discount coupons or even have the manager hook you up! Order a small and get a large =D it's good for business provided it doesn't hurt their bottom line and gets you back in the door again win win win! Smart business owners know this that is why loyalty programs exist! I was just raised you hold doors for people, you offer to help someone who is fumbling around with their things, you say please and thank you, you tip at least 20% (I'v been known to tip the bill which is really what I strive to do since I know most tip based jobs earn less than min wage and rely on those tips). It really is just being a good person! Take it or leave it for what it is. I watch someone not even leave a tip after being rude after their server being so nice and trying to make their experience good. Some people just are so ungrateful and others SO grateful. I don't eat fast food very often but last time at Wendys I gave them a $10 tip omg they upgraded everything and handed me like 50 free coupons for frostys that usually are only for promotions. I didn't expect anything I just know they work hard for at or about min wage 2am serving rude annoying people. It's just paying forward in my eyes. I once had my card declined during a layover after ordering food and I was so upset I didn't know what to do I had no cash and felt terrible I thought I'd miss my flight and be stuck there till I figured out how to pay, my server paid my bill. I'll never forget the amount of concern he had for me, I felt so bad I think about it every time I am out how hard they work for so little and how caring most are for their guests. I even told him he didn't have to do it and he insisted and I practically fell to tears and thanked him a hundred times before leaving. I had the money, my bank was closed and saw it as an unauthorized charge so it got declined. My lesson learned was always have some cash while traveling AND always help out the people who serve you when you can. Such a great guy he wouldn't even give me the information to send him the money back so I told him I'd pay it forward! To this day I have stayed true to that and do my best when I can to help people working hard to better their lives and helping others =D I felt bad at the time, but I feel good about the experience now because I kept my word of paying it forward and never having to be in that situation again!
