I mentioned a little bit about the history. Fenwicks is long established with a commitment to luxury (different from other retailers) and a perfect opportunity to learn. Also it might be good to mention that they started as a family business which is still shown in their team.
Debenhams has many services e.g wedding service, beauty counters, travel money, click & collect, order in store and bra fitting service. There is always staff on the shop floor to ask for help and the beauty counters provide help for a particular subject.
