No, you’re good.
Back when my workplace had regular potlucks, most would go all out with homemade dishes. Those who did not or could not cook would bring a fancy bakery cake or something else store-bought but appropriate.
One person - and she did this every time - would bring a single, 2-liter bottle of a non-name brand soda. Often it proudly displayed its low price as part of the label - I think it was 79 cents at the time.
And yeah, she was usually first in line, filling up her plate to the edges. It became a running joke.
