Confused

Cust: can I get your opinion?
EM: sure!
Cust: I've got a strapless bra on but I think it's a bit big (pulls the cup out at the side and holds her arms out) I don't know if I need to try the cup size down again?
EM: if you put your arms down... To be honest it looks fine, you'll always have a gap when you pull it but if we go down, your going to get an extra boob on the top of your larger side.
Cust: because the lady said the other one looked big
EM: ok
Cust: and these two. The 34F felt bigger than that one (points to a bra on the stool)
EM: (has a look at bras on the stool, there's the strapless in the smaller cup size and a 32FF in the other bra) the other bra is bigger round the back... and this (holds up the strapless from the stool) is the smaller size
Cust: but.. it was big in the cup
EM: a firmer bra will hold the cup to you. This is the smaller cup size in the strapless, so you can try that and see...
Cust: oh ok

(In the stockroom)

EM: VG, what strapless did you give to the lady in number four? I'm not sure she even knows what day it is...
VG: I gave her the 34E over the top of the door
EM: right? She just got me to check the F and said that she's been given that because the other one looked big?
VG: so she got me to check that and get another one and then kept it on and got you to check it, thinking it was the smaller size... Right...
