I have been a loyal worker for 1 1/2 years and this is the thanks I get?

As the title says I have worked at a local chic fil a for 1 1/2 years, but I still have not been promoted, not even a pay raise. Yet many of the new hires are getting handed out promotions like candy. One of my friends started working their 2 months ago and he is already senior trainer (a position I did not know even existed). I worked 70hr weeks all summer and work the max 24 hrs per week I can during the school year. Then this past week they have the audacity to question why I am looking for another job. I guess one of my friends told them. This whole situation just ticks me off. I try my hardest, but that’s still not enough.
