Thessaloniki both had very similar scores. Male population stated
inspection while female respondents encircled serving as the
statement with lowest ranking. Younger population recognized

PCA outputs for the data matrix are shown in Fig. 1. Dimension
reduction by PCA separated the observed factors into two distinct
directions: kitchen related and non-kitchen related statements.
PC1 (kitchen related component) has high positive loadings (>0.5)
on hygiene, cooking, quality, approval, storage and temperature
with no negative loadings. PC2 (non-kitchen related component)
has high positive loadings (>0.5) on employees, inspections and
negative loading on serving of food.
