Between surgical face masks selling for Sh10 and Sh20, Peter Mwania, a mechanic in Nairobi preferred the cheaper one.
The 45-year-old resident of Tena estate in Embakasi never asked why the masks had different prices. But last week on his way to Industrial Area where he works, Mwania asked for his usual Sh10 face but the vendor told him she only sells the Sh20 ones and explained the difference.
