I do this too, that is how I trained them to wait until we are done bc they know they will get something. I have a tall breed. When my son was little, if I did not train them on this they would be at his high chair eating off his tray any time I turned to get something. Then we had the year the Thanksgiving turkey disappeared off the counter. Or when I had to get a bread box bc one liked loaves of bread. And my mom still has not forgiven another for swiping her leftovers she heated up and then left on the counter while she ran upstairs for something. My favorite memory is the year I took them home for holiday and forgot that my sister was afraid of dogs and I walked into the kitchen and she was giving everybody a piece of pizza to "make friends."
