When we are traveling in the US, we have a car so it is easy to bring supplies from one sit to another, but we often don’t have a lot. We usually only shop for one week’s worth of food at a time, and we aren’t ones to need a lot of variety, so we don’t end up with big ‘backlogs’ of unused food that we are lugging from sit to sit. We may have some cooking oil and a few items that are longer lasting that get packed up.
I don’t drink coffee but my husband does, and in our experience, most hosts drink it as well and offer us to use theirs. He will buy some too usually. If he didn’t have any for the first day, it wouldn’t bother him so we would’t ask whether it is available.
Most of the time, we don’t do our shopping until that first day we arrive–unless we are in a very rural area, a good supermarket usually isn’t far and it’s a simple trip-- or perhaps the next day, if we are doing an overlap, and arriving the night before the hosts leave.
We have been doing intermittent fasting for over a year now so we usually don’t eat until around 1130 or noon for the first time, so if we don’t have any food for that first morning, it’s fine since we aren’t eating yet anyway. And we will get to the store later on.
There are times we will do a full shopping on the way to a sit. For example, our current sit is in a pretty remote area where the closest major supermarkets are an hour away. So we stopped off in that town on the way and stocked up for two weeks.
As for international sits, we are almost always arriving the day before the host leaves, and they almost always prepare a meal that evening, and when they don’t, we grab something ourselves. and will usually just shop the next day.
So for us, this isn’t usually a conversation we have with the hosts. I get that some sitters don’t want to worry about shopping that first day for a variety of reasons, but we don’t find it an issue. I get what you mean about it feeling awkward asking,as you are right that it can come off as sounding like you are requesting they provide these items for you.
I guess depending on what someone prefers to eat, even if not traveling by car, there are lots of different things that don’t take up too much room and can easily be transported in a suitcase or backpack.
