Sometimes teachers bring treats so that the students will gush appreciation, giving the teacher a feeling of, well, almost power. That shouldn't be the reason anything is given. If you struggle with disappointment because students would state that they would prefer this or that, get over it. If you are looking for "appropriate" responses to your generosity, offer the same treats to teacher friends. For the most part, they are aware that nothing had to be brought, and they will respond positively. I bring Jolly Ranchers once in a blue moon, but that's it. Some students would rather have _____. I simply shrug my shoulders and state that they are not obligated to take a JR, it is their choice. Most important part of the verbal exchange is that it is honest. They would prefer a Snickers, as would I, but the JR is all I have, so take it or leave it - it's not a popularity contest, nor do I care if they take my treat, properly "thank" me, or appreciate my effort. I saw JR's, bought them, and will share what I have if they want it - it isn't a personal affront if they decline, even with a comment, because I wasn't trying to "buy" popularity. I simply didn't think it was fair for me to eat the JR's in front of them without having enough to share. I can't control their manners, but I still remember my mom telling me not to eat in front of others if I didn't bring enough to share. The truth is that the only person's actions we can control is our own. Just what I was taught. . .
