anyway, i've a good impression of prima deli staff.
once i bought some confectionery & gave a big note (was
thinking about something else, thus distracted) & walked away
without taking the change.
the cashier dashed out of the shop & knocked into my back when
i heard "excuse me!!!" & stopped on the spot. both of us were
so embarrased. 
then i thanked her & took my change.
........wonder if she is still working there......
(my story a bit looooong,
)
