Late Middle Ages

In the Late Middle Ages in the Netherlands, were there already shops where clothing, furniture and food was for sale (NL)?

At crossings of trade roads (over land and water) often, places were set up for (year)markets. These places were often occupied only a part of the year, but the most important ones grew out to permanent settlements and eventually complete towns...

What did they eat at the Crannogs in Scotland (UK)?

We have found traces of spelt and emmer wheat on site and barley. Also, a wide range of nuts and berries, including cloud-berry, raspberry, strawberry, brambles, sloes and wild cherries. Hazelnuts are in great abundance. Wild carrots, wild cabbages, wild garlic and thyme, and meat from domestic animals such as sheep and cow. Butter and cheese were found, but So far no fish bones have been found, but we have net weights.
