It may be those were pilot meals that the pilots refused (some pilots will not eat the meals provided to them). Possibly the FA decided to offer to you instead since you were the only one in F and EXP. Last week I had a FA serve me BOB that was catered from the pilots but the pilots weren't hungry. I've noticed that some FAs sans food will still serve as normal. The only exception is PDBs (one FA actually offered me something on the ground but I didn't want him to do anything against corporate policy and I could wait until in the air for my Tito's).
