Removal company etiquette

This is our 3rd time selling but our first time using a removal company as we've done our previous 2 moves ourselves but having 2 young children this time round, we wanted to take a bit of stress off.

As things like our kettle will be packed, is there a specific etiquette regarding drinks/food for the removal company as we won't be able to offer them a coffee - will they even have time to drink? We can pick ourselves a coffee up after dropping our kids off at childcare but do we get the removal guys one as well? I'd have to ask them prior what they drink 🤣

Is there anything we should be doing while they're loading the van (aside from the obvious cleaning)? Do we offer to buy them lunch or do they tend to bring their own?

Sorry if this sounds stupid but we don't want to be inconsiderate or considered rude! Thanks for any advice 😊
