I do buy takeaway coffee, and at a burger place, I might use ketchup sachets if that's all they have. But for use at my home, I buy bottles of ketchup, not sachets. Given a choice, why would I choose to succumb to waste? It's like a company forcing me to use mayo sachets at home, rather than buying a bottle, because it makes them more money. That's not convenience, that's profiteering at the expense of the environment and the consumer.
