Is it legal not to display prices?

I go into a barber and there are no prices listed, is this legal?

Looking at https://www.ccpc.ie/business/help-for-business/guidelines-for-business/hairdressers/
‘There are laws for the mandatory display of prices for a number of specific types of service, including hairdressers and barber shops, so that consumers can easily compare prices without committing themselves to purchasing in that premises.

‘The relevant legislation is called the Charges (Hairdressing) Display Order, 1976 and is enforced by the CCPC.

The price information must be accurate and include all taxes such as VAT. If the prices you charge for services or products are different to the prices displayed, this constitutes a Misleading Price Indication, and you may be in breach of the Consumer Protection Act. The CCPC has the power, if such breaches are found, to take enforcement action, including the issuing of a compliance notice.’
