is wrapped, and his money is received. If particular attention is 
not paid to the facilities for performing these functions, serious 
difficulties are likely to be encountered. The number of exits neces- 
sary will depend upon the size of the business, the special conditions 
of the trade (whether it is steady or fluctuates considerably), and 
the methods used in

checking. When one 
experienced person 
does the checking, 
wrapping, and 
cashiering, it requires 
about a minute to 
take care of the av- 
erage customer, but 
when two persons do 
this work it can be 
done in practically 
half the time. In 
some cases three per- 
sons or more are used, 
and this again re- 
duces the time re- 
quired. 
Whether one, two, 
or three persons are 
stationed at the exit 
depends entirely upon 
conditions, as the 
principle involved is 
the same. When two 
persons are used, one 
usually checks and 
receives the money 
while the other wraps 
the merchandise. The 
employee who wraps 
usually calls the arti- 
cles to the cashier, 
the latter entering the 
amounts on the add- 
ing machine. When three persons are used, the first usually adds 
and totals the purchases, the second takes the money, and the third 
wraps. This plan is the least satisfactory, as it requires an extra 
handling of the merchandise. It should not be used unless it be 
impossible, because of the store arrangement, to add another exit,
