Almost all hikers will need to resupply during their thru hikes and section hikes. Many times they will eat and drink at restaurants in town.
To help ensure goodwill towards hikers that will follow you long after you’ve gone, please adhere to any rules that may be posted, including, but not limited to, no bare feet and no backpacks allowed inside.
Clean yourself up before visiting eating and drinking establishments. Hiker funk can be a turnoff to the locals, who frequent those businesses regularly. Remember to tip your servers, many of whom work for minimum wage.
And if you choose to drink, drink responsibly, so the owner maintains good relations with his community.
