Review the following scenario.

Promotional deal on 1 yoga mat was $19 on the website of Salford Sports and Fitness Store. After checking this, Sera and her husband Adam went to their nearest store to buy 2 mats. Sera picked the mats and straight went to checkout counter for billing. Upon scanning the mats, cashier asked Sera to pay $78 ($39 each), upon which Sera confronted the cashier saying that mat is on special offer at their website. Cashier confirmed from store manager but was strictly told that mat is for $39 each.

Upon checking the shelf where all yoga mats were stocked, display price for same mat was $39. Due to this, Adam encountered floor supervisor stating that company website has promotional price on the same mat, and he should be charged $38 for 2 mats.

Store manager offered manager discounted price of $69 and walked away leaving the matter in cashier hands.

Express in your words the impact this would leave on Sera and Adam. Also highlight how the store manager should have assessed this situation further and what actions he/she would have taken to provide better customer service and gaining repeat business.
