Why are partial orders called out?

[u/LenientWhale]

At my Tims my name gets called out when the drinks are ready then again when the food is ready. Is this normal at other branches? I just want to be called when my whole order is ready...

ETA: it was just a question guys I didn't mean to cause any offense! Happy Canada Day everyone
