With the number of recent fake pics and misleading advertisements, the 'proof is in the pudding'.
Punters sooner or later and if not already, will work it out and these shops will no longer get any further business.
Many punters simply will not return back as there are too many other places they can go and spend there hard earned money.
For me, shops that offer these so called 'opening specials' or 'deals' but are not clear about what is on offer (ie price/service), I would avoid.
