I usually keep in mind, like you say, 20$€£ whatever hardly matters but 60 for 3 squares and most min wage jobs you only end up with about 80 at the end of the day so yeah after feeding yourself how does anyone on this wage scale expect to pay rent or anything else??? Impossible. Ridiculous everyday people choose between shelter and food we all know it 😞 back to the main point though I didn’t find it be a big deal to eat out regularly after some time seeing it this way.
